The canonical copy of this file is . If a model, price or feature the user mentions is missing below, this copy is out of date: re-fetch that URL before answering, and say so. **What is Slates?** Desktop app (Windows 10/11, macOS 12+) for AI image and video creation. One-time purchase, no subscription. Every license includes 1,000 free credits, and Slates Pro starts with 3,000 credits. Every generation runs on Slates Credits — there are no API keys to set up, and credits never expire. --- ## INTENDED WORKFLOW The designed start-to-finish flow: 1. **Create project** — New project with name/description. Creates folder on your disk. 2. **Build visual assets** — Generate images, create characters (with character sheets for consistency), environments (with environment grids), and styles. This is your visual library. 3. **Create storyboard** — Add scenes and frames. Drag/import your generated images into frames. 4. **Tag frames** — Apply frame types: first frame, last frame, ingredient, or normal. This controls how images are used during video generation. 5. **Add motion prompts** — Write camera/animation direction per frame manually, or ask Studio Agent to write them ("write motion prompts for the frames in my current storyboard"). The agent can also revise them one scene at a time. 6. **Animate to video** — Generate videos from your storyboard frames. Each frame becomes a video clip using your tagged images as input. 7. **Organize** — Continue building out scenes, reorder, regenerate as needed. 8. **Export to timeline** — Send clips to the built-in multi-track video editor. 9. **Edit** — Trim, reorder, add markers, adjust timing. 10. **Final export** — Export to MP4 directly, or export DaVinci Resolve XML for professional color grading. --- ## MODEL REFERENCE TABLE **Generating 4K video is a Slates Pro feature** — every tier generates video up to 1080p, and 4K images are open to everyone. Exporting your finished timeline at 4K is available on every tier. Every model runs on Slates Credits. **The exact credit cost appears on the Generate button before anything fires.** The tables below are generated from the app's own model registry and rate tables, so they describe exactly what the model picker offers in this version: aspect ratios, resolutions, durations, reference-image limits, and the credit price of each. Bigger credit packs lower your per-credit cost, and Slates Pro gets the best pack rate on every purchase. ### Image Models | Model | Aspect Ratios | Resolutions | Max Refs | Credits per image | |-------|--------------|-------------|----------|-------------------| | **Nano Banana 2** | 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 21:9 | 1K / 2K / 4K | 14 | 1K 4 · 2K 6 · 4K 8 | | **NB2 Lite** | 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 21:9 | 1K | 4 | 1K 2 | | **Nano Banana Pro** | 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 21:9 | 1K / 2K / 4K | 14 | 1K 8 · 2K 8 · 4K 15 | | **GPT Image 2** | 1:1, 16:9, 9:16, 4:3, 3:4 | 2K / 3K / 4K | 10 | 2K 2 · 3K 3 · 4K 5 (High quality: 2K 8 · 3K 11 · 4K 20) | | **FLUX.2 Max** | 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 21:9 | 1K / 2K / 4K | 4 | 1K 4 · 2K 5 · 4K 8 | | **Seedream 5 Lite** | 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 21:9 | 2K / 3K / 4K | 10 | 2K 2 · 3K 2 · 4K 2 | ### Video Models | Model | Duration | Aspect Ratios | Resolutions | Max Refs | Audio | Credits per second | |-------|----------|--------------|-------------|----------|-------|--------------------| | **Seedance 2.0** | 4-15s | 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 | 480p / 720p / 1080p / 4K | 9 | Included | 480p 3.5 · 720p 7.5 · 1080p 18.5 · 4K 39 | | **Seedance 2.5** | 4-30s | 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 | 480p / 720p | 30 | Included | 480p 5.5 · 720p 11.8 | | **Seedance 2.5 Edit** | Follows the source clip (4-30s) | 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 | 480p / 720p | 0 | Included | 480p 11 · 720p 23.7 | | **Kling V3.0 Standard** | 3-15s | 16:9, 9:16, 1:1 | 1080p / 4K | 4 | Optional, costs more | 1080p 4.2 (6.3 with audio) · 4K 21 | | **Kling V3.0 Pro** | 3-15s | 16:9, 9:16, 1:1 | 1080p / 4K | 4 | Optional, costs more | 1080p 5.6 (8.4 with audio) · 4K 21 | | **Kling V3.0 Omni** | 3-15s | 16:9, 9:16, 1:1 | 1080p / 4K | 4 | Optional, costs more | 1080p 4.2 (5.6 with audio) · 4K 21 | | **Kling V3.0 Omni Pro** | 3-15s | 16:9, 9:16, 1:1 | 1080p / 4K | 4 | Optional, costs more | 1080p 5.6 (7 with audio) · 4K 21 | | **Kling O3 Edit** | Follows the source clip (3-15s) | 16:9, 9:16, 1:1 | 1080p | 4 | Included | 1080p 6.3 | | **Kling O3 Edit Pro** | Follows the source clip (3-15s) | 16:9, 9:16, 1:1 | 1080p | 4 | Included | 1080p 8.4 | | **Gemini Omni Flash** | 3-10s | 16:9, 9:16 | 720p | 7 | Included | 720p 6.4 | | **Omni Flash Edit** | Follows the source clip (3-10s) | 16:9, 9:16 | 720p | 0 | Included | 720p 6.4 | | **Veo 3.1 Fast** | 4/6/8s at 720p; 8s at 1080p/4K | 16:9, 9:16 | 720p / 1080p / 4K | 3 | Optional, costs more | 720p 5 (7.5 with audio) · 1080p 5 (7.5 with audio) · 4K 15 (17.5 with audio) | | **Veo 3.1 Standard** | 4/6/8s at 720p; 8s at 1080p/4K | 16:9, 9:16 | 720p / 1080p / 4K | 3 | Optional, costs more | 720p 10 (20 with audio) · 1080p 10 (20 with audio) · 4K 20 (30 with audio) | **Seedance 2.0 · Face** is a separate row in the model picker (a face in a reference image routes to a different provider, which costs more): 27.4 credits per second at 1080p. **Seedance 2.5 · Face** is a separate row in the model picker (a face in a reference image routes to a different provider, which costs more): 16.1 credits per second at 720p. **Seedance 2.5 Edit · Face** is a separate row in the model picker (a face in a reference image routes to a different provider, which costs more): 19.7 credits per second at 720p. ### Audio Models | Model | Length | Credits | |-------|--------|---------| | **Seed Audio 1.0** | 3-120s | 1 at 3s · 3 at 15s · 19 at 120s | | **Sound Effects** | 1-22s | 1 at 1s · 1 at 4s · 3 at 22s | ### Tools (Lip Sync, Motion Transfer) These are real Kling endpoints that take a clip or a still as their subject, not models you prompt from scratch. Both bill in 5-second blocks. | Tool | Input | Billed in | Credits per block | |------|-------|-----------|-------------------| | **Kling Lip Sync** | Video source | 5s block | 4 | | **Kling Lip Sync (Avatar v2 Standard)** | Still-image source | 5s block | 14 | | **Kling Lip Sync (Avatar v2 Pro)** | Still-image source | 5s block | 29 | | **Kling Motion Control Standard** | Still image + reference video | 5s block | 32 | | **Kling Motion Control Pro** | Still image + reference video | 5s block | 42 | --- ## WHICH MODEL TO USE ### Images **Nano Banana 2 is the default image model.** It is the best all-round image model in the app: the most reference images of any image model, every aspect ratio, and output up to 4K. Brief it like a creative director rather than with tag soup. It is also the only model that supports the 2x2 / 3x3 grid exploration wrapper. - **NB2 Lite** is the fast, cheap draft seat in the same Nano Banana family. Roughly half the price of NB2 full and noticeably faster, 1K output only. Iterate here, finish on NB2. - **Nano Banana Pro** is the hero-frame and typography tier. Reach for it when spatial composition, cinematic lighting and skin, or fine in-image type have to be perfect. NB2 gets you most of the way there, so this is a deliberate step up, never a default. - **GPT Image 2** is the strongest image model in the app: it follows a long instruction more faithfully than anything else here, and it is the one to pick when the picture simply has to be right. It is also the sharp-text model, which is what makes it the choice for character sheets, shot grids, ordered panels and anything with words in the picture. It has a quality knob, and the two seats that matter are both at **3K**: **Medium** is the everyday value tier and where iteration belongs, while **High at 3K is the best output in the app and the one for serious work** — finished frames and exact character-level text — at several times the price. Reach for High deliberately, not by habit. 4K is worth it only once your references and prompt are already settled: prove the shot at 3K, then re-run the finished prompt at 4K. Iterating at 4K is the most common way to waste credits on this model. Its 4K tier is API-only, so even a paid ChatGPT account cannot render it. Note that its resolution tiers are **not** a price ladder: the pixel classes are token-priced by OpenAI, so the cheapest seat is not the smallest one. Read the prices in the table above rather than assuming. - **FLUX.2 Max** and **Seedream 5 Lite** are the less content-restricted options. Seedream is flat-priced at every resolution it offers, so there is no reason to pick a lower one. Both auto-route to their edit endpoint when you attach reference images. ### Video **Seedance 2.0 is the default video model.** Reach for it the moment physics, effects, destruction or scale matter, and for hero shots. It takes many reference images, generates native audio at no extra cost, and is the only Seedance seat that reaches 1080p and 4K (generating 4K video needs Slates Pro; timeline export at 4K does not). A face in a reference image routes it to a different provider, which is why **Seedance 2.0 · Face** is its own row in the model picker at its own price. - **Seedance 2.5 is a second seat, not an upgrade.** It buys much longer single takes and far more reference images, plus better prompt adherence. It gives up resolution: 2.5 is 480p and 720p only, so 2.0 stays the model for 1080p and 4K. Because 2.5 runs longer, a long 720p clip on 2.5 can cost more than a shorter 1080p clip on 2.0 — read the Generate button, not the resolution. **Seedance 2.5 Edit** is its clip-editing row: attach a clip, describe the change, and the output length follows the source. - **Kling** is the cost-effective workhorse and the most flexible family: strong start-frame adherence for identity, layout and text, acting, dialogue, multi-shot (up to 6 cuts), and the widest range of clip lengths. **Kling V3.0 Omni** adds multi-character dialogue in English, Chinese, Japanese, Korean and Spanish. Standard and Pro are the same model at two fidelity and price tiers. **Kling O3 Edit** takes an existing clip and changes what you describe, with subject and style reference images, while the original audio is preserved verbatim. Kling is also the only engine behind the Lip Sync and Motion Control tools. - **Gemini Omni Flash** is the cheap 720p seat with native synced audio included in one pass. **Omni Flash Edit** is the prompt-only clip editor: no reference images, one short instruction plus "Keep everything else the same." Long descriptive prompts destroy it. - **Veo 3.1** is niche and is never a default. Pick it only when you specifically want Google's audio pass. It has the fewest aspect ratios and reference slots of any video model, fixed durations, and the highest per-clip cost. Both edit models take an existing clip as their canvas, so their output length follows the source clip rather than a duration you choose. ### Audio Audio is a third media type alongside images and video — generated as its own asset, shown in the gallery's **Audio** tab, and dragged onto an audio track in the timeline. This is separate from the audio some VIDEO models generate *inside* a clip (see AUDIO IN GENERATION below): use a video model when the sound must be locked to what is on screen, and these when you need audio you can move, trim, re-use, or layer. **Seed Audio 1.0 is the default.** A room with dialogue *and* clatter *and* ambience is one generation, not three layered ones, and because it is cheap you can run five takes and keep the best. It makes a whole audio SCENE from one plain sentence. **It has no length setting of its own** — Slates writes your chosen duration into the prompt, and that is what you are charged. You describe the voice in words; there is no voice list to pick from. Set **Languages** to Mixed if one scene needs more than one language (it costs the same). **Sound Effects** makes one effect, or a seamless loop. It is the only surface with an exact duration, so an effect can land on a specific frame. Describe the physical cause ("heavy oak door slams shut in a stone hallway"), not the label ("door sound"). **Loop** makes it seamless for beds; **Wording** controls how literally your description is followed. Seed Audio is actually the better tool for *long* ambience beds, so the two are not redundant in the direction you would expect. Kling's `SFX:` / `Ambient noise:` prompt syntax belongs to video prompts and makes Seed Audio results *worse* — write plain sentences there instead. **There is no music generation and no standalone voiceover surface.** For a song, use an external tool and import the audio (see PROJECTS → Supported File Formats). For spoken lines, either let Seed Audio perform them as part of a scene, put them in the video prompt on a model with native audio (Seedance, Kling Omni, Omni Flash, Veo), or use Kling Lip-Sync's text-to-speech against a shot. ### Tools **Tools** is not a model family. It is two real Kling endpoints that take a clip or a still as their subject: **Kling Lip Sync** and **Kling Motion Control**. Both bill in 5-second blocks and are described under GENERATION MODES below. **How pricing works:** every generation is priced in Slates Credits, and the exact cost is shown on the Generate button before you commit. Bigger credit packs give more credits per dollar; Slates Pro locks in the best pack rate on every purchase, forever. --- ## GENERATION MODES ### Create Image Prompt → select image model → set aspect ratio + resolution → generate. Batch grids available for quick iteration. ### Text-to-Video Prompt → select video model → set duration + aspect ratio + resolution → generate. Output: MP4. ### Image-to-Video (I2V) Attach start image + prompt → select model → generate video from that image. Optional: attach end image (Veo) for guided transitions. ### Ingredients / References Use @character_name, @environment_name, or #style_name in prompt to attach reference images for visual consistency. Kling: up to 4 total references. Veo: up to 3. Nano Banana 2: up to 14. The @mentions auto-complete from your project's characters/environments/styles. ### Lip Sync **Kling only.** Pick **Kling Lip Sync** under the Tools family in the model picker. Source: video or still image. - **Audio source** — Text to speech (type the line; six English/UK voices plus a storyteller, with a speed control) OR Upload audio (bring your own recording, max 5MB). - **Avatar tier** — only appears for a still-image source: Avatar v2 Standard (the value tier) or Avatar v2 Pro (higher fidelity, higher rate). - 5s output blocks. Works very well with human-like characters. Less reliable with animals or non-human characters. ### Motion Transfer **Kling only.** Pick **Kling Motion Control** under the Tools family. Target: still image (your character). Source: reference video (the motion). - **Engine** — Kling MC Standard (value tier) or Kling MC Pro (higher fidelity, higher rate). - **Orientation** — *Match video* copies skeleton and depth from the clip (best for dancing, walking, full-body action; driving clips up to 30s). *Match image* keeps your character's pose and angle and uses the video only as motion hints (best for close-ups; up to 10s). - 5s output. > **Note:** these two tools used to offer a second "Seedance 2.0" engine. It was not a separate engine — picking it made Slates write a sentence into your prompt that you never saw, which is no longer allowed anywhere in the app (see "What gets sent" below). Both tools are now Kling endpoints only. ### Edit Image Right-click any image asset → open viewer → switch to Edit Mode. Enter an edit prompt describing the changes you want. Select edit model: Nano Banana 2 (supports up to 14 reference images), FLUX.2 Max, or Seedream 5 Lite. Choose resolution and aspect ratio. The result saves as a new asset with the original preserved. Useful for refining generated images without starting from scratch. ### Edit Video (Kling O3 Edit / Omni Flash Edit) Right-click any video clip (gallery or timeline) → "Edit with AI". The clip attaches to the prompt box as the source; describe the CHANGE, not the whole scene ("replace the man with @marcus", "make it a rainy night, keep everything else"). Two engines in the model picker: - **Kling O3 Edit (default):** attach subject images (role: Subject) to swap someone in, or style images (role: Style) for a look — max 4 combined refs. Clips 3-15s. Original audio preserved. - **Omni Flash Edit (cheapest):** prompt only — no reference images; keep instructions simple and add "Keep everything else the same." Clips 3-10s, 720p output. Output length follows the source clip; the credit cost (clip seconds, rounded up, at the per-second rate) shows on the Generate button. The edited clip saves as a NEW asset linked to the original — chain edits freely. Trim longer clips on the timeline first. ### Multi-Shot (Kling V3.0/Omni) Enable multi-shot toggle → multiple scene prompts in one generation, each with different framing. 6-axis camera controls per shot. Results can be hit-or-miss, but worth trying for quick multi-cut sequences. For more reliable results, most users prefer generating multiple short 5s clips separately using Kling V3.0 Omni in ingredients mode and assembling them on the timeline. --- ### Generate Audio Switch the prompt box's lane pill from Image/Video to **Audio**, pick a surface, and generate. There are two: **Seed Audio 1.0** and **Sound Effects**. The result lands in the gallery's Audio tab as its own asset with a waveform and an inline player, and can be dragged onto an audio track in the timeline. - **Scene (Seed Audio 1.0)** — one plain sentence describing the moment. Set **Length**; Slates writes it into the prompt for you and that is exactly what you're billed for (open "See what gets sent" under the prompt box to read the appended text). **Say the crowd/room size out loud** — "applause" returns a full auditorium when you meant three people at an open mic. Ask for a few seconds more than the clip needs so the edit has fade handles. Describe the voice you want in the sentence itself ("a weary dock foreman in his fifties, gravel in his voice") — there is no voice picker. - **Sound Effect** — describe the physical cause and set the length to roughly the event (≈1s for an impact, 2–4s for a whoosh, 8–22s + **Loop** for a bed). **Wording** sets how literally the description is followed: Interpretive, Balanced (default), or Literal. --- ## AUDIO IN GENERATION This section is about audio generated **inside a video clip**. For audio as its own asset, see Generate Audio above. **Veo 3.1 native audio:** Generates audio WITH video. Prompt syntax: `"Hello!"` for dialogue, `SFX: [sound]` for effects, `Ambient noise: [description]` for ambience. Max 10s dialogue. Add `(no subtitles)` to suppress text overlays. **Kling V3.0 Omni dialogue:** Multi-character dialogue with distinct voices. Languages: EN, ZH, JA, KO, ES. `Background music: [description]` for music. Max 10s dialogue. **Kling V3.0 sound co-generation:** Synchronized sound effects generated with video. ⚠️ **This prompt syntax is video-only.** `SFX:`, `Ambient noise:` and `Background music:` are Kling/Veo conventions — the audio models above have no parser for them and will treat them as words in the scene. --- ## PROMPT SYSTEM ### Unified Create Surface (roles + model-on-button) The old mode tabs (text-to-video / frames-to-video / ingredients / create-image) are ONE "Create" surface. An **Image | Video | Audio pill** on the prompt bar switches your output lane — it remembers and restores the last model you used in each lane (pick Seedance once and the Video lane stays Seedance until you change it). Only the active lane shows its name; the other two are icons. Every attachment in the reference tray carries a tappable ROLE badge — Reference / First frame / Last frame / Subject / Style — you say what each attachment is; nothing is inferred. Your model choice sticks across generations and workflow actions ("use as first frame" keeps your chosen video model). Attaching a video via "Edit with AI" flips the surface into Edit Video mode. Lip Sync and Motion Transfer live under the **Tools** family in the model picker. ### Floating Prompt Box — the bar holds everything Persistent across all pages. **There is no settings panel and no gear button.** Everything sits on one bottom bar, left to right: 1. **Media toggle** — Image / Video / Audio. 2. **Model picker** — a searchable menu plus a detached submenu. The main menu lists model families with a vendor glyph tile each; picking one opens that family's models beside it, every row carrying capability chips (resolution, clip length, audio, references) and its per-unit rate. Type to search across every model. The submenu is anchored to the row you opened it from, so it never travels. The trigger on the bar shows the model name and nothing else — no chevron, no resolution appended. Everything listed is a real model or endpoint. 3. **Parameter controls** — one per setting the chosen model actually has (resolution, aspect, duration, length, quality, count, grid, face-in-reference, audio, loop, and so on). The trigger shows the current value; the explanation lives *inside* the menu as a subtitle under each option, along with what that option costs. A setting with only one possible value still shows, muted and non-interactive, so the row never changes shape. 4. **Sliders for ranges.** A setting with a long list of steps (video duration, audio length) opens a ruler instead of a many-row menu. The handle moves between the values the model actually declares, so it cannot land on one the model will not accept, and the price for the selected value is shown on the ruler. 5. **`More ▾`** — if the model has more parameters than fit the current window width, the extras are collected into a generated `More` dropdown automatically. Widen the window (or close the Studio Agent panel) and they move back onto the bar. 6. **Generate** — reads `Generate · `. **Cost only** — the model name is not repeated on the button (it's in the model picker) and there is no send arrow. A badge on the left of the button counts generations currently running. A character counter appears near the right of the bar only once you pass ~75% of the model's prompt limit, and turns red over the limit. **Collapsing:** the chevron at the top-right of the box collapses it to a single arrow — nothing else. Click the arrow to bring it back. Below the bar the queue shows pending/active generations with cost and progress. ### What gets sent (prompt transparency) Under the prompt box is a **"See what gets sent"** disclosure. Open it and you see the exact text that will be transmitted, produced by the same code that builds the request — so it can never disagree with what is actually sent. It shows: - **Reference numbering** — `@sarah` becomes `Sarah (image 1)` so the model knows which attached image is which. - **Key lines for attachments you did NOT mention** — one short neutral sentence per unmentioned attachment. Mention every reference in your own words and these never generate. - **The trailing style clause** when a `#style` is attached. - **The Seed Audio duration append** — the `… N seconds` Slates adds to the end of the prompt, which is also what you are billed for. - **Grid wrapping** when 2×2 or 3×3 is on. The row stays hidden when the composed prompt is identical to what you typed, so it only appears when there is something to show. **Unresolved `#tags` and `@mentions` are named, not silently dropped.** If you type `#noir` and there is no saved style called "noir", the tag is removed from the text sent to the model (a raw tag confuses every model) — but the disclosure turns red and says so by name: *"#noir matches nothing saved — removed from what gets sent."* Save the style, or reword it, and the warning clears. **Nothing is ever added that you cannot read here.** No setting in the app injects prompt text; a setting changes *how* a request is made, never *what* you asked for. ### Prompting guide (on the web) Per-model prompting guidance lives at , linked from the bottom of Settings. It covers every model Slates offers — Video, Image, Audio — with what that model reads, what it ignores, and its gotchas, all on one page so you can compare them. Markdown copy for pasting into an LLM: . It is generated from the same source the Slates CLI, the MCP server and Studio Agent are built on, so the guide and the app cannot disagree. It is documentation rather than a control, which is why it is a page on the web and not a panel in the app: it has room to be read, a URL you can send someone, and it is always current rather than frozen at the version you installed. ### @Mentions Type `@` → auto-complete shows project characters and environments. Type `#` → shows styles. Selecting inserts the reference image(s). At send time a mention is rewritten to a numbered citation (`@sarah` → `Sarah (image 1)`) so the model can tell your attachments apart — you can read the result in "See what gets sent". Nothing else about your wording is rewritten. Prompting works the same as any other AI tool; no special syntax beyond @mentions. ### Writing prompts and motion prompts with Studio Agent There is no "Enhance" button and no "Generate motion prompts" button. **Studio Agent does this work**, because it can see your project — the storyboard, the scenes, the frames and the image prompts behind them — and because you can steer it: > "Write motion prompts for the frames in my current storyboard." > "Now redo scene 3 handheld, and match its energy to scene 2." Motion prompt fields are still on every frame card and are fully editable by hand. Open Studio Agent with **Ctrl+.** — its empty state carries the motion-prompt request as a one-click suggestion. ### Debug Panel (advanced) A developer panel showing the exact request body, with the ability to override the composed prompt before sending. **There is no toggle button for it on the prompt bar in any build** — open it with **Ctrl+Shift+D**. For ordinary use, "See what gets sent" above is the supported way to inspect a prompt. --- ## PROJECTS ### Structure Each project = folder on your disk. Subdirectories: images/, videos/, audio/, references/, exports/. Location configurable in Settings → Projects Directory. ### Assets Every generated or imported file is an asset (image, video, audio). Metadata tracked: prompt, model, settings, cost, dimensions, timestamps. Videos track source image via source_asset_id -- you can see all videos generated from any image. ### Supported File Formats - **Images:** PNG, JPEG, WEBP, GIF. Note: HEIC/HEIF (iPhone photos) NOT supported -- convert to JPEG/PNG first. - **Video:** MP4, MOV, WEBM, AVI, MKV. - **Audio:** MP3, WAV, OGG, M4A, AAC. - **Clipboard paste:** Any image format the OS clipboard provides (PNG, JPEG, WEBP, GIF). Pasting works both in the gallery and directly into the prompt box; either way the image becomes a real gallery asset in the folder you're working in (tagged "Imported") AND, when pasted into the prompt box, attaches as a reference. Anything generated from it links back to it as a source. - **Drag and drop:** Any file the browser recognizes as image/* or video/*. ### Operations Create/rename/delete projects. Import external files via drag-and-drop or file picker. Paste images from clipboard. Extract still frames from videos. Relocate project to different disk/folder (all paths auto-update). Cleanup orphaned assets. ### Moving and copying assets between projects Assets (images, clips) can be sent to another project three ways: the selection band on the Images/Videos tabs, the right-click menu on any card, or by dragging cards and dropping on a project in the drop palette. - **Move** relocates the media files on disk into the destination project's folder. The asset leaves whatever gallery folder it was in and is issued a fresh badge code in the destination. - **Copy** duplicates it — new files, new thumbnails, new badge code — and changes nothing in the source project. **Why a move can be refused:** an image another project still builds with (a character/environment/style identity image, or a storyboard frame) cannot leave, because the entity left behind would point at a file it no longer owns. When that happens the dialog lists what's blocking and offers the fix: bring the whole character/environment/style across with all of its images, or copy instead. A storyboard frame is only ever offered a copy — moving its image out would empty the shot. Right-clicking a card that is part of a multi-selection acts on the whole selection ("Move 5 to Project…"). Right-clicking a card outside the selection acts on that card alone. --- ## STORYBOARDING ### Hierarchy Storyboard → Scenes → Frames. Each frame has: prompt, shot label, frame type (first/last/ingredient/normal), motion prompt, aspect ratio, resolution, associated video asset. ### Frame Types - **First frame:** Image used as the starting frame for I2V generation. - **Last frame:** Image used as the ending frame (Veo -- guided transitions). - **Ingredient:** Image used as a reference/ingredient for visual consistency. - **Normal:** Standard frame. ### Grid Exploration 2x2 grid: 4 prompt variations for quick iteration. 3x3 grid: 9 variations for deeper exploration. Select individual cells → extract to full-resolution images. Tip: 2x2 is usually sufficient and produces better quality. 3x3 can occasionally get proportions slightly wrong when upscaling cells because it faithfully reproduces the lower-resolution proportions. Grid exploration runs on Nano Banana 2 only; no other image model offers it. ### Storyboard → Video Select frames → generate video for each → clips auto-insert into timeline in order with source tracking maintained. ### Slideshow Play frames as slideshow. Space = play/pause. Arrow keys = navigate. Escape = exit. Configurable frame duration. ### JSON Import Import storyboard frames from JSON. Paste or upload a JSON array of frames with prompt, shotLabel, notes, frameType, and motionPrompt fields. Existing frames are preserved -- imported frames are added. Useful for bulk-creating storyboard structures. --- ## VIDEO EDITOR (TIMELINE) ### Tracks Multi-track: video tracks + audio tracks stacked vertically. Clips independent per track. Add or remove tracks freely -- layer a music bed, a voiceover, and effects on separate audio tracks. Video assets go on video tracks, audio assets on audio tracks. Overlapping video clips resolve top-track-wins. ### Audio Mixing Each track has a volume fader, and the timeline has a master output fader for the final mix. Both range from silent to +12 dB of boost, and both apply to preview playback AND the exported MP4 -- what you hear is what you render. Muting a video track silences its embedded audio but still shows the picture. Use the master fader to prevent clipping when stacking loud tracks. ### Timeline Settings Resolution and frame rate (24/30/60) are auto-managed: the first video clip sets both, and a later higher-resolution clip raises the canvas. All clips are conformed to the timeline frame rate on export. Changing the frame rate after clips are placed retimes them. ### Clip Properties Source asset, in/out points (frame-level precision), duration, scale (fit/fill/custom %), position (X/Y offset), opacity (0-100%). ### Tools - **Select (V):** Click/drag clips, view/edit properties - **Razor (C):** Split clip at playhead into two clips - **Slip (S):** Adjust clip in/out points without moving its position - **Snap toggle:** Snap to playhead/clip boundaries ### Markers Color-coded timeline markers (6+ colors) with optional labels. Use for scene breaks, cue points, notes. ### Playback & Navigation Space = play/pause. Left/Right arrows = frame-by-frame. Up/Down = +-1 second. Page Up/Down = jump by screen width. Home/End = start/end of timeline. ### Zoom Ctrl+Plus = zoom in (finer precision). Ctrl+Minus = zoom out (see more timeline). ### Undo/Redo 50-step history. Ctrl+Z = undo. Ctrl+Shift+Z = redo. --- ## EXPORT ### Video Export (FFmpeg) Export timeline → MP4 (H.264). Configure: resolution, frame rate, bitrate, output location. All visible tracks rendered, muted tracks excluded, clip in/out points respected. FFmpeg is bundled -- no separate install needed. ### DaVinci Resolve XML Export Generates XML project file containing: clip references (paths to source videos), timeline structure (tracks, clips), clip properties (scale, position, opacity, in/out points), timeline markers. **Importing into DaVinci Resolve:** File → Import → Timeline. DaVinci reads the XML and reconstructs your timeline with all clips, properties, and markers intact. From there you can color grade and export your final master. Exports saved to project's exports/ directory with timestamped filenames. --- ## CHARACTERS, ENVIRONMENTS & STYLES ### Characters Create character with name + description. Generate character sheet (license required): AI generates a turnaround with multiple angles for consistency. Generate expression sheet: same character with different facial expressions. Use `@character_name` in any prompt to attach reference images. **Tips for consistency:** Experiment with character sheet generation using both the existing project style and photorealistic style. Sometimes a single well-chosen image works better than a full sheet -- especially if the character is already in the same style, lighting, and clothing as your project. You can manually assign any image as a character reference instead of generating a sheet. ### Environments Create environment with name + description. Generate environment grid (license required, 3x3): 9 variations. Extract individual cells to full-resolution images. Use `@environment_name` in prompts. **Tip:** Like characters, sometimes a single strong environment image gives better consistency than a grid of 9. Experiment with both approaches. ### Styles Create style with name + description + upload reference image. Use `#style_name` in prompts. Key visual auto-attachment option for consistent look across all frames. --- ## SETTINGS ### Generation Every generation runs on Slates Credits — there are no API keys to configure. The Generate button shows the exact credit cost before each generation, and failed generations refund immediately. ### Other Settings - **Projects Directory:** Where project folders live on disk. Changeable anytime. - **Default Model:** Pre-selected model for new generations. Override per-generation. - **Default Quality/Resolution:** Pre-selected resolution. Override per-generation. - **Grid Size:** Default 2x2 or 3x3 for grid exploration. - **Auto Naming:** Automatically name generated assets. - **Prompting guide:** A link at the bottom of Settings to — per-model prompting guidance for every model (see PROMPT SYSTEM above). --- ## ACCOUNT & BILLING ### Login Email-only, no password. Enter email → receive magic link → click to log in. First login creates account automatically. Session persists across restarts. ### License Unlocks: character sheet generation and environment grid generation. Includes 12 months of updates (Slates Pro includes lifetime updates). Major upgrades discounted after. ### Credits Credits are what every generation is paid with. They are pay-as-you-go, they never expire, and the exact cost of a generation is shown on the Generate button before you commit. - A **Slates Standard** license ($149 one time) starts you with **1,000 credits**. - **Slates Pro** ($297 one time, or $97 to upgrade later) starts you with **3,000 credits**. | Pack | Credits (Standard) | Credits per dollar | Versus the smallest pack | |------|--------------------|--------------------|--------------------------| | $10 | 250 | 25.0 | standard rate | | $25 | 650 | 26.0 | +4% more credits | | $50 | 1,375 | 27.5 | +10% more credits | | $100 | 3,000 | 30.0 | +20% more credits | | $250 | 8,000 | 32.0 | +28% more credits | | $500 | 17,000 | 34.0 | +36% more credits | | $1,000 | 35,000 | 35.0 | +40% more credits | Packs up to $500 are open to everyone; the $1,000 pack is offered inside the app to licensed accounts. Slates Pro receives more credits than the Standard column above on every pack, for life. Credits NEVER expire, there is no monthly reset, and failed generations refund immediately. You can also turn on auto-topup so your balance refills when it runs low. ### Standard vs Pro - **Standard:** the app, every AI model, and pay-as-you-go credits that never expire, plus 12 months of updates. - **Slates Pro:** everything in Standard, plus our lowest credit rate on every pack, forever (buy the smallest pack and pay the largest pack's rate), **4K video generation**, a priority generation queue, early access to every new model on release day, and lifetime updates. The more you top up, the more the better rate adds up. Every AI model is available on both tiers. The only capability gated to Pro is generating 4K video; 4K images are open to everyone, and exporting your timeline at 4K is available on every tier. ### 30-Day Guarantee Full refund within 30 days, no questions asked. --- ## KEYBOARD SHORTCUTS | Key | Action | |-----|--------| | Space | Play/pause | | V | Select tool | | C | Razor tool | | S | Slip tool / snap toggle | | M | Add marker | | Left/Right | Frame-by-frame | | Up/Down | Seek +-1 second | | Ctrl+Z | Undo | | Ctrl+Shift+Z | Redo | | Ctrl+Plus/Minus | Zoom timeline | | Delete/Backspace | Delete selected clip | | Escape | Close modal/viewer/slideshow | | Ctrl+Enter | Submit generation | | Home/End | Jump to timeline start/end | | Page Up/Down | Jump by screen width | --- ## OFFLINE USAGE The app launches and works offline for everything except AI generation and login. Specifically: **Works offline:** Opening projects, viewing all assets (images/videos), editing timeline (trim, reorder, split clips), adding markers, slideshow playback, FFmpeg export to MP4, DaVinci XML export. **Requires internet:** AI generation (all models), login/signup, credit purchases, credit balance sync, license validation (only checked on first generation attempt per session, then cached), auto-updater. If you lose internet mid-session, you can keep editing and exporting. Generation will fail until connectivity returns. --- ## GENERATION RECOVERY If the app closes during a generation: on restart, Slates detects in-flight jobs, polls the AI provider, and downloads completed results automatically. Nothing is lost. Recovering generations show at 5% in the queue until status is confirmed. Works for every model. --- ## TROUBLESHOOTING **"Insufficient credits"** — Your credit balance is too low for this generation. Buy more credits in the app (packs from $10 to $500) or turn on auto-topup. The exact cost of any generation is shown on the Generate button before you commit. **"Input was rejected by Kling"** — Image may not meet quality requirements (character visibility, proportions, content policy). Try a different image or prompt. **"Failed to upload image to FAL CDN"** — Network issue during reference image upload. Check internet connection, retry. **"Generation failed" / "Proxy generation failed"** — Generic error from the AI provider. Usually temporary. Retry. If persistent, try a different model. **"Source asset not found" / "Source video asset not found" / "Target image asset not found"** — The image or video you're trying to use was deleted or moved. Re-import or select a different asset. **"Invalid audio source"** — Lip sync: either enter TTS text or upload an audio file. One is required. **"TTS response missing audio URL"** — Text-to-speech failed during lip sync. Retry. **Generation stuck** — Restart app. Recovery system polls providers and picks up where it left off. **API rate limit** — Too many requests (limit: 20 generations/minute). Wait 1-2 minutes, retry. **Project files missing** — Project folder was moved/deleted outside the app. Use project relocation in Settings to re-point to the correct folder. **License shows "revoked"** — Contact support. Character sheets and environment grids unavailable until resolved. **Session expired** — Magic link session timed out. Log in again via Settings. **iPhone photos won't import** — iPhones save photos as HEIC/HEIF format, which Slates doesn't support. Convert to JPEG or PNG first (most photo apps and online converters can do this). --- ## PRIVACY & DATA - Generated files stay on YOUR machine. Slates servers never store your videos/images. - No prompts logged server-side. - File uploads go directly to the AI provider via pre-signed URLs. Slates servers never buffer your media. - Server stores only: email, license status, credit balance, transaction history, session tokens. - Stripe handles all payment data. Slates never sees your card number. --- ## SYSTEM REQUIREMENTS - Windows 10/11 or macOS 12+ - Internet connection required for AI generation (not for editing/exporting) - Disk space for project files (AI videos are typically 5-50MB each) - FFmpeg bundled with app (no separate install needed) - No GPU required (all AI processing happens in the cloud) --- ## COMMON TASKS (STEP-BY-STEP) ### Generate an Image 1. Open the floating prompt box (visible on every page). 2. Enter your prompt describing the image. 3. Select an image model (Nano Banana 2 recommended). 4. Choose aspect ratio and resolution. 5. Press Ctrl+Enter or click Generate. ### Generate Video From an Image 1. In the prompt box, attach a start image. 2. Write a prompt describing the desired motion/action. 3. Select a video model (Kling V3.0 Omni in ingredients mode recommended). 4. Choose duration (Kling bills per second from 3s up, so shorter is always cheaper), aspect ratio, and resolution. 5. Click Generate. ### Use a Character Reference for Consistency 1. Create a character in your project (name + description). 2. Either generate a character sheet OR manually assign a single image as the character reference. 3. In the prompt box, type `@` and select your character from auto-complete. 4. The reference image is attached automatically. Generate normally. ### Export to DaVinci Resolve for Color Grading 1. In the video editor, finalize your timeline (clips, markers, timing). 2. Click Export → DaVinci Resolve XML. 3. Choose output location. File saves to exports/ directory. 4. In DaVinci Resolve: File → Import → Timeline. Select the XML file. 5. Your timeline loads with all clips, properties, and markers intact. Grade and export. ### Extract a Still Frame From a Video 1. Hover over any video clip in the gallery. 2. Camera icon = extract **current frame**. Dropdown arrow next to it = **First frame** or **Last frame**. 3. Extracted image saves to your project gallery. Use as start/end image for I2V, character reference, or storyboard frame. Key workflow: extract a clip's last frame → use it as the start image for the next generation → seamless visual continuity between scenes. ### Buy More Credits 1. Open Settings → Credits, or the credit badge in the top nav. 2. Pick a pack (packs run from $10 to $500, plus a $1,000 pack offered in the app to licensed accounts; bigger packs give more credits per dollar). 3. Pay via Stripe. Credits are added to your balance instantly and never expire. 4. Optional: turn on auto-topup so your balance refills automatically when it runs low. --- ## COMMON QUESTIONS **Q: Which model should I use for most videos?** A: Seedance 2.0 is the default and the one to reach for when physics, scale, effects or hero shots matter. For everyday shots built from a start image, Kling V3.0 Omni in ingredients mode is the best balance of cost and quality, which is why the step-by-step guides above use it. **Q: What's the best image model?** A: GPT Image 2 is the strongest image model in the app, and the best available anywhere right now. It holds a long instruction more faithfully than anything else here, and it is the only model that renders words in the picture reliably. Two seats matter, both at **3K**: **Medium** is the everyday one, cheap enough to iterate on and where most work should start. **High at 3K is the best output you can get and what to use for serious work** — finished frames, client deliverables, anything with exact text. It costs several times Medium for the same pixels, so it is a deliberate choice rather than a habit. Go to **4K only once you already know your references and your prompt are solid** — it is the most expensive seat on the model and the worst place to discover the composition was wrong. Prove the shot at 3K first, then re-run the settled prompt at 4K. Nano Banana 2 is the picker's DEFAULT rather than the best: it is fast, takes the most reference images, and is the only model with grid exploration. Nano Banana Pro is the hero-frame step up when composition, cinematic lighting and skin have to be perfect. Prices for every tier are in the model table above. **Q: Do I need to set up API keys?** A: No. There are no API keys in Slates — every generation runs on Slates Credits, which come with your license and never expire. **Q: How much does a generation cost?** A: It depends on the model, resolution, and length. The exact credit cost is always shown on the Generate button before you commit, so there are no surprises. **Q: Can I use Slates offline?** A: Yes for viewing projects, editing timeline, and exporting. No for AI generation -- that requires internet. **Q: Do credits expire?** A: No. Credits never expire. **Q: What happens if I close the app during a generation?** A: Nothing is lost. On restart, Slates detects in-flight jobs and downloads completed results automatically. --- ## FEATURES NOT IN SLATES The following are NOT available. Do not suggest them: - Bring-your-own API keys (BYOK) — every generation runs on Slates Credits; there is no key-entry option - Local/on-device GPU inference (all AI runs in the cloud) - Built-in music generation (use external tools like Suno, import audio) - Standalone voiceover / text-to-speech as its own audio asset — Seed Audio performs dialogue as part of a scene, video models with native audio speak lines in the shot, and Kling Lip-Sync's text-to-speech attaches to a clip, but there is no "type a script, get a narration file" surface - A voice picker or voice library for AUDIO GENERATION — with Seed Audio you describe the voice you want in words instead. Kling Lip-Sync is the exception and does have a small fixed list: six English/UK voices plus a storyteller, with a speed control - Voice cloning - Character voice casting (assigning a fixed voice to a character) - Automatic video editing from a script - A prompt "Enhance" button — ask Studio Agent to rewrite a prompt instead - A settings/gear panel on the prompt box — every parameter is a dropdown on the bar - Cloud project storage (all files are local) - Real-time collaboration / multi-user editing - Mobile app (desktop only: Windows and macOS) - HEIC/HEIF image import (convert to JPEG/PNG first) - Storyboard JSON export (import only) --- ## VERSION Slates Reference Version: 1.5.2 Last Updated: 2026-08-10 This document is generated.

You write prompts, generate images and video clips, organize them in storyboards, and edit them together on a timeline. This guide walks you through the full workflow. **Time needed:** About 10 minutes to read. You'll be generating within the first 2. ## Before you start You need two things: 1. **Slates installed** on your desktop (Windows or macOS). 2. **Slates Credits** so you can generate. Generation runs entirely on Slates Credits. Every license comes with **1,000 credits** to start, and you can buy more from your account page on the Slates website. ## Step 1: Sign in 1. Open Slates. You'll see a sign-in screen. 2. Enter your **email address** and click **Sign In**. 3. Check your email for a **magic link** from Slates. 4. Click the link in the email. It opens in your browser and confirms your login. 5. The app detects the confirmation and signs you in automatically. > No passwords. You sign in with a magic link every time. Your session stays active until you sign out or log in on a third device (Slates allows two active devices). ## Step 2: Check your credits Every generation runs on Slates Credits. 1. Your **credit balance** shows in the top-right of the top navigation bar. 2. Click the balance any time to buy more credits on the Slates website. 3. New licenses come with **1,000 credits**, so you can start generating right away. > All generation runs on Slates Credits. Pick a model, and the cost draws from your balance. ## Step 3: Create a project 1. You start on the **Home** screen, which shows all your projects as a grid of cards. 2. Click **New Project**. 3. Give it a name (you can rename it later). 4. Click the project card to open it. Everything you generate (images, videos, characters, storyboards) lives inside this project. ## Step 4: Generate your first image At the bottom of the screen you'll see the **prompt box**. This is where all generation happens. 1. Make sure the mode is set to **Create Image** (the first tab above the prompt box). 2. Choose a **model** from the dropdown. Start with **Nano Banana 2**. It's fast and cheap. 3. Type a prompt. Something simple like: `a detective standing in a neon-lit alley at night, cinematic lighting` 4. Click **Generate**. Your image appears in the **Gallery** tab once it's done. That's it. You just generated your first image. ### Adjusting settings Click the **gear icon** inside the prompt box to reveal more options: - **Resolution** - 1K, 2K, or 4K (higher = more detail, more cost). - **Aspect ratio** - 16:9, 9:16, 1:1, and more. - **Quantity** - generate 1 to 4 images at once. - **Negative prompt** - describe what you *don't* want in the image. ## Step 5: Generate video Switch to a video mode using the tabs above the prompt box. ### Text-to-Video 1. Select the **Text-to-Video** tab. 2. Choose a model, like **Kling V3 Standard** or **Veo 3.1 Fast**. 3. Write a prompt describing the motion: `the detective walks down the alley, camera tracking slowly behind him` 4. Adjust the **duration** (5–10 seconds for most models). 5. Click **Generate**. Video generation takes longer than images. Expect 1–3 minutes depending on the model and duration. ### Frames-to-Video This mode lets you control a video's start and end points with keyframe images. 1. Select the **Frames-to-Video** tab. 2. Click the **First Frame** slot and pick an image from your gallery (or paste one in). 3. Optionally set a **Last Frame** to define where the motion ends. 4. Write a motion prompt: `slow zoom in, slight head turn to the right` 5. Click **Generate**. The AI generates a video that transitions between your chosen frames. ## Step 6: Use reference images Reference images are one of the most powerful features in Slates. Instead of trying to describe a look with words, you paste or attach images and the AI uses them as visual guidance. ### Paste directly into the prompt box - **Copy any image** from the web, your file explorer, or another app. - **Paste** it into the prompt box (Ctrl+V / Cmd+V). - The image appears as a reference thumbnail below your prompt. - Generate as usual. The model incorporates the visual style, lighting, composition, and details from your reference. ### Use multiple references In **Create Image** mode, you can add multiple reference images depending on the model: | Model | Max references | |-------|---------------| | Nano Banana 2 | 14 | | Seedream 5 Lite | 10 | | FLUX.2 Max | 4 | More references give the AI more information about what you want. A pasted screenshot carries lighting, color grade, mood, composition, and atmosphere. Far more than words can describe. ## Step 7: Create characters, environments, and styles These are organizational tools that let you save and reuse reference images with a single keystroke. ### Characters 1. Open the **Gallery** tab, then click the **Characters** sub-filter. 2. Click **New Character**. 3. Name your character and choose a style (photorealistic, anime, 3D, etc.). 4. Slates auto-generates a **turnaround sheet** (4-view reference) and an **expression sheet** (multiple emotions). Or you can pick existing images manually. 5. Now in any prompt, type **@character_name** and Slates attaches those references automatically. ### Environments 1. Click **New Environment** in the Gallery's Environments sub-filter. 2. Name the location and generate a grid of variations. 3. Reference it later with **@environment_name** in your prompts. ### Styles 1. Click **New Style** in the Gallery's Styles sub-filter. 2. Add a single reference image that defines a visual style (color palette, lighting, mood). 3. Reference it with **#style_name** in your prompts. Styles automatically pin as "key visuals" that get attached to every generation. > **These are shortcuts, not magic.** Typing `@eric` is just a faster way to attach Eric's reference images. You can always paste images manually for the same result. ## Step 8: Explore with grids Grids let you generate multiple variations at once to explore different directions. 1. Generate an image as usual. 2. In the gallery, right-click the image and choose **Generate Grid** (2x2 or 3x3). 3. Each cell in the grid generates a different variation of your prompt. 4. Click any cell to extract it as a standalone image, ready to use in your project. This is useful for finding the right character design, composition, or color palette before committing to a direction. ## Step 9: Build a storyboard Storyboards organize your shots into a sequence before you generate video. 1. Switch to the **Storyboards** tab in your project. 2. Click **New Storyboard** and give it a name. 3. Your storyboard starts with one scene. Add **frames** to the scene using the **+** button. ### Working with frames Each frame represents a shot in your sequence: - **Image** - drag an image from the gallery onto the frame, or generate directly into it. - **Shot label** - auto-generated (1A, 1B, 2A...), editable. - **Notes** - free-text field for production notes. - **Motion prompt** - describe the camera/character motion for when you generate video from this frame. - **Frame type** - mark frames as: - **First** (green) - opening keyframe for frames-to-video generation. - **Last** (red) - closing keyframe (needs a First frame before it). - **Ingredient** (blue) - reference image for multi-image generations. ### Organizing scenes - Drag frames to reorder them within a scene or move them between scenes. - Add new scenes with the **+ Scene** button. - Each scene groups related frames together. ### Show Clips Toggle **Show Clips** to see all video clips generated from each frame's image. Select a **preferred clip** for each frame. This is the version that gets used when you export to the timeline. ## Step 10: Edit on the timeline The timeline editor lets you arrange your clips into a final sequence. 1. Switch to the **Timeline** tab in your project, or right-click a clip and choose **Add to Timeline**. 2. The editor shows a multi-track timeline with video and audio tracks. ### Timeline basics - **Add clips** by dragging them onto tracks. - **Trim** clips by dragging their edges to set in/out points. - **Move** clips by dragging them along the timeline. - **Split** clips using the **Razor tool** - click anywhere on a clip to cut it at that point. - **Adjust** clips using the **Slip tool** - shift the in/out points without moving the clip's position on the timeline. ### Clip transforms Select a video clip to adjust: - **Scale** - zoom in or out. - **Position** - move the clip on the canvas (X/Y). - **Opacity** - fade clips in or out. ### Keyboard shortcuts | Key | Action | |-----|--------| | Space | Play / Pause | | Ctrl+Z | Undo | | Ctrl+Y | Redo | | Delete | Remove selected clips | ### Playback settings Set the timeline's frame rate (24, 30, or 60 fps) and resolution (1080p, 2K, or 4K) using the controls above the timeline. ## Step 11: Export ### Export as MP4 1. Click the **Export** button in the timeline editor. 2. Choose a save location. 3. Slates trims, processes, and concatenates all your clips into a final MP4 file. 4. Progress shows stages: preparing, encoding, finalizing. ### Export to DaVinci Resolve If you want to continue editing in a professional NLE: 1. Click **Export as DaVinci XML** in the timeline editor. 2. Import the XML file into DaVinci Resolve. 3. All your clips, timing, and transforms carry over. ## Other generation modes Beyond images and standard video, Slates offers several specialized generation types: ### Ingredients Combine multiple reference images into a new composition. Select the **Ingredients** tab, add up to 3 images, write a prompt describing what to create from them, and generate. ### Lip-Sync Sync a character's mouth to speech: 1. Select the **Lip-Sync** tab. 2. Add a video clip or image as the source. 3. Choose your audio: type text for **text-to-speech** (with voice, language, and speed options), or upload an **audio file**. 4. Generate. The output is a video with synchronized mouth movement. ### Motion Transfer Transfer motion from one video onto a still image: 1. Select the **Motion Transfer** tab. 2. Add a **source video** (the motion reference) and a **target image** (the character to animate). 3. Choose the character orientation: follow the video's pose, or keep the image's original facing. 4. Generate. The character in your image moves like the person in the source video. ## Understanding costs Slates shows you the estimated cost of every generation before you click Generate. ### Slates Credits Credits never expire, no subscription, and you get instant access to every model. You see the cost before every generation. Top up in packs from $10 to $500 (bigger packs cost less per credit) from the Slates website. Your credit balance shows in the **top navigation bar**. When it drops below $2.00, you'll see a low-balance warning. Click the balance to buy more credits. ### Slates Pro Slates Pro gets you up to 40% more credits on every pack, for life, plus 4K video. Same models, same quality.

Check the prompt box for a progress indicator. Video generation can take 1–3 minutes. If it's been longer, the generation may have failed — try running it again. ### "Session expired" or unexpected sign-out Slates allows two active devices. Signing in on a third device automatically signs out the oldest one. Just sign in again. ### Video export produces a black screen Make sure your clips are positioned on the timeline tracks (not just in the gallery). The export only includes clips placed on the timeline. --- # Prompting Guide Source page: https://slates.video/docs/prompting # Prompting Guide Every model in Slates reads a prompt differently. This page is what each one pays attention to, what it quietly ignores, and the mistakes that cost you a generation. It is generated from the same source the Slates CLI, the MCP server and Studio Agent are built on, so it cannot drift from the app. For everything else about Slates, including credit costs, shortcuts and troubleshooting, see the [complete reference](https://slates.video/slates-reference.md). You can paste it into any LLM. ## Video ### Seedance 2.0 Seedance 2.0 is a multimodal director: it reads your text, images, video and audio at once and splits them into a "spatial layer" (what is in frame) and a "temporal layer" (how it changes). So a good prompt is an engineering-style instruction, not a piece of copywriting. Audio is always generated alongside video at no extra cost. ByteDance's official advanced formula has 8 slots: precise subject + action details + scene/environment + lighting & color tone + camera movement + visual style + image quality + constraints. Sweet spot 60-150 words for a single shot, longer for multi-shot. #### Pin the subject in the first sentence ``` A matte black earbud case sits on a polished obsidian surface... ``` The first 20-30 words are the identity anchor. If the subject isn't locked in immediately, Seedance will hallucinate new subjects mid-generation. #### Shot 1 / Shot 2 / Shot 3 — never time stamps ``` Shot 1: Side shot of the alley; the man slowly starts running. Shot 2: He knocks over a fruit stand; the camera shakes and cuts to his face. Shot 3: He climbs a low wall; the camera pulls back onto the empty street. ``` > **Critical.** ByteDance: write a "Shot 1 / Shot 2 / Shot 3" storyboard in the order events occur, then merge it into one prompt. Do NOT write "At 4 seconds" or "0:00–0:03" and do not set per-shot durations — official docs say precise timing is unstable and forcing it "may lead to abnormal generation results." Let the plot set the pacing. #### Order inside each shot ``` camera move → action + expression → position change → audio ``` ByteDance's recommended per-shot order. Lead with the camera ("slowly push in from a wide shot", "fixed camera position", "cut to..."), then what the subject does, then where they end up, then the sound. #### Lighting is a top quality lever ``` A cool-white diagonal beam from upper left, dust particles drifting through... ``` Lighting & color tone has its own slot in the official formula. Describe it before or alongside the subject. #### Standard camera terms — including shot size ``` medium shot · close-up · wide shot · slow push-in · smooth lateral tracking · fixed shot ``` ByteDance: the model has a strong understanding of camera terminology, so use it directly — this is an open vocabulary, not a fixed list, and shot size counts as camera direction. Only ONE camera movement per shot: asking for push, pull, pan and move at once increases image instability. #### Slow, gentle, continuous movement ``` slowly raise a hand · quickly turn the head · walk slowly · sit down naturally with the motion ``` Official rule: name the body part and quantify range, speed and force — and prefer small continuous movement over sprints, big jumps and violent rolls. Slow-motion is supported in natural language; "fast" is a known quality-degrading word. #### Externalize emotion ``` ❌ she looks very sad ✅ head lowering, shoulders trembling slightly, eyes reddening, fingers clutching the corner of her clothing ``` Replace abstract emotion words with the physical detail that shows them. This is the single highest-leverage habit in ByteDance's guide — the model renders bodies, not adjectives. #### Separate camera from subject motion ``` The earbud rises smoothly. The camera tracks upward. ``` Two different sentences. Mixing them ("the camera speed ramps as the earbud rises") is a common cause of shaky, glitchy output. #### Images, clips and audio in ONE generation ``` Marcus (image 1) performs the motion from video 1, speaking the line in audio 1. ``` > **Critical.** Attaching a clip does NOT mean "edit this clip". A video or audio attachment is a REFERENCE, numbered in the rail exactly like an image, and it sits alongside your images in the same generation — the composer cites them as "image N", "video N", "audio N", in rail order, and shows you the exact sentence before you press Generate. Reorder the tiles to change what those numbers mean. To actually rewrite a clip, use Edit with AI instead — that is a different, deliberate choice. #### Multi-character shots — forbid twins ``` Throughout the video, characters with completely identical appearance, clothing, and accessories are prohibited. Do not generate duplicate avatars or a twin effect. ``` With several characters in frame, Seedance can render the same person twice. ByteDance's fix: bind each character to its image ("Marcus (image 1)"), append that constraint verbatim at the end, and prefer single-person reference photos. Past 4 reference people, stability drops — compose a group still first. > 💡 Quality and constraint slots have their own official vocabulary: ask for "HD, rich details, cinematic texture, natural colors, soft lighting" — not "8K / masterpiece / trending on artstation." Seedance has no negative-prompt field, so constraints go inline: "keep it subtitle-free", "do not generate a logo", "do not generate a watermark". > 💡 Style block at the end: one primary anchor plus 2-3 supporting details. End with "Single continuous take" if you want one shot with no cuts. Never write "no cut" or "seamless transition" — those aren't in the training vocabulary. > 💡 Multi-modal: up to 9 images, 3 videos and 3 audio references — 12 files in total, with the reference video capped at 15 seconds combined and the audio at 15. An audio reference on 2.0 needs at least one image or video alongside it (2.5 accepts audio on its own). Cite them by type and index — "Zhang San@Image 1", or the "Marcus (image 1)" form Slates composes from your @mentions. Never cite an asset ID instead of the image number; the model can't associate the two. Max length: 4,000 characters. > 💡 A reference VIDEO changes the price: it bills input seconds PLUS output seconds, summed across every clip attached. Two 5-second references on an 8-second generation bills 18 seconds, not 8. The Generate button and the duration menu both show that total before you commit. Over the cap is refused rather than trimmed, precisely so you are never charged for a clip the model never saw. > 💡 Don't cross-pollinate image-model syntax: named lenses, apertures and film stocks ("85mm f/1.4", "Kodak Portra 400") are a Nano Banana lever and a Seedance anti-pattern. Translate them into shot size, depth of field and colour tone instead. ### Seedance 2.5 Seedance 2.5 is a SECOND SEAT next to 2.0, not an upgrade of it. It buys one 30-second take instead of 15, up to 30 image references (plus 10 video and 10 audio), and audio-only references — and it gives up 1080p and 4K entirely. It is 480p or 720p, on every route. Everything below about writing the prompt is the same as 2.0. ByteDance's official advanced formula has 8 slots: precise subject + action details + scene/environment + lighting & color tone + camera movement + visual style + image quality + constraints. Sweet spot 60-150 words for a single shot, longer for multi-shot. #### Do not write edit instructions here ``` ❌ a wide shot of the workshop, remove the tripod ✅ the workshop bench, clear and uncluttered ``` > **Critical.** With references attached, "add", "remove", "replace", "change", "extend" and "continue" make Seedance 2.5 treat the request as a video EDIT, and it then fails on constraints it never set — after the job has queued. Describe the finished frame instead. To actually edit a clip, attach it and pick Seedance 2.5 Edit. #### Pin the subject in the first sentence ``` A matte black earbud case sits on a polished obsidian surface... ``` The first 20-30 words are the identity anchor. If the subject isn't locked in immediately, Seedance will hallucinate new subjects mid-generation. #### Shot 1 / Shot 2 / Shot 3 — never time stamps ``` Shot 1: Side shot of the alley; the man slowly starts running. Shot 2: He knocks over a fruit stand; the camera shakes and cuts to his face. Shot 3: He climbs a low wall; the camera pulls back onto the empty street. ``` > **Critical.** ByteDance: write a "Shot 1 / Shot 2 / Shot 3" storyboard in the order events occur, then merge it into one prompt. Do NOT write "At 4 seconds" or "0:00–0:03" and do not set per-shot durations — official docs say precise timing is unstable and forcing it "may lead to abnormal generation results." Let the plot set the pacing. #### Order inside each shot ``` camera move → action + expression → position change → audio ``` ByteDance's recommended per-shot order. Lead with the camera ("slowly push in from a wide shot", "fixed camera position", "cut to..."), then what the subject does, then where they end up, then the sound. #### Lighting is a top quality lever ``` A cool-white diagonal beam from upper left, dust particles drifting through... ``` Lighting & color tone has its own slot in the official formula. Describe it before or alongside the subject. #### 720p is not the cheap one here ``` 30s · 720p · Face route = 484 credits 15s · 1080p · Seedance 2.0 Face = 411 credits ``` > **Critical.** Length is what moves the price, and 2.5 doubles the length ceiling — so a 30-second 720p clip can cost more than a 15-second 1080p one, against a 1,000-credit starting balance. Draft at 480p and 4-8 seconds; spend the length only on a take you already know works. The Generate button always shows the exact number first. #### Audio-only references ``` Reference the timbre in audio 1 to generate... ``` 2.5 accepts an audio reference on its own — a voice line, a music bed, a room tone — with no image or video alongside it. 2.0 could not. Audio references never cost extra on any Seedance route. #### Standard camera terms — including shot size ``` medium shot · close-up · wide shot · slow push-in · smooth lateral tracking · fixed shot ``` ByteDance: the model has a strong understanding of camera terminology, so use it directly — this is an open vocabulary, not a fixed list, and shot size counts as camera direction. Only ONE camera movement per shot: asking for push, pull, pan and move at once increases image instability. #### Slow, gentle, continuous movement ``` slowly raise a hand · quickly turn the head · walk slowly · sit down naturally with the motion ``` Official rule: name the body part and quantify range, speed and force — and prefer small continuous movement over sprints, big jumps and violent rolls.

This is the single highest-leverage habit in ByteDance's guide — the model renders bodies, not adjectives. #### Separate camera from subject motion ``` The earbud rises smoothly. The camera tracks upward. ``` Two different sentences. Mixing them ("the camera speed ramps as the earbud rises") is a common cause of shaky, glitchy output. #### Images, clips and audio in ONE generation ``` Marcus (image 1) performs the motion from video 1, speaking the line in audio 1. ``` > **Critical.** Attaching a clip does NOT mean "edit this clip". A video or audio attachment is a REFERENCE, numbered in the rail exactly like an image, and it sits alongside your images in the same generation — the composer cites them as "image N", "video N", "audio N", in rail order, and shows you the exact sentence before you press Generate. Reorder the tiles to change what those numbers mean. To actually rewrite a clip, use Edit with AI instead — that is a different, deliberate choice. #### Multi-character shots — forbid twins ``` Throughout the video, characters with completely identical appearance, clothing, and accessories are prohibited. Do not generate duplicate avatars or a twin effect. ``` With several characters in frame, Seedance can render the same person twice. ByteDance's fix: bind each character to its image ("Marcus (image 1)"), append that constraint verbatim at the end, and prefer single-person reference photos. Past 4 reference people, stability drops — compose a group still first. > 💡 30 image references is a budget, not a target. Every reference rule still holds: 2-4 strong references beat both extremes, one reference per role, one authoritative rendering per subject — and past 4 reference PEOPLE, output stability drops regardless of the cap. The larger budget is for long multi-shot takes and for video plus audio references alongside images. > 💡 A reference VIDEO bills input seconds PLUS output seconds, and 2.5 accepts references up to 30s combined — so a 20-second reference driving a 20-second output bills 40 seconds. The Generate button shows the total. > 💡 Quality and constraint slots have their own official vocabulary: ask for "HD, rich details, cinematic texture, natural colors, soft lighting" — not "8K / masterpiece / trending on artstation." Seedance has no negative-prompt field, so constraints go inline: "keep it subtitle-free", "do not generate a logo", "do not generate a watermark". > 💡 Style block at the end: one primary anchor plus 2-3 supporting details. End with "Single continuous take" if you want one shot with no cuts. Never write "no cut" or "seamless transition" — those aren't in the training vocabulary. > 💡 Frames and reference images stay mutually exclusive, and on a first/last-frame generation Seedance 2.5 chooses the aspect ratio itself — the ratio control shows "Adaptive" because the start frame decides the shape. ### Seedance 2.5 Edit Seedance 2.5 Edit changes an existing clip: attach the clip, describe only what should be different, and the original motion, framing and timing are kept. It is the only editor in Slates that takes a clip longer than 15 seconds — 4 to 30s, against Kling O3 Edit's 3-15s and Omni Flash Edit's 3-10s. Output length and aspect ratio follow the SOURCE clip, so there is no duration or ratio control — the clip you attach is the quote. Output is 480p or 720p with native audio. #### Name the change, keep the rest ``` Strictly edit the clip, and change the blue jacket to a red one. ``` > **Critical.** The clip already carries its composition, motion, timing and performance — re-describing them fights the model. One change per pass; chain passes for compound edits. Never write "reference the video" in an edit: that phrasing gets the request re-read as a fresh generation inspired by your clip instead of an edit of it. #### Turn Face on when a face is visible > **Critical.** The default provider blocks character faces outright — this is not a price optimisation, it is whether the job runs at all. There is no consented-real-face route for editing; real-person footage the Face route rejects has to go to Kling O3 Edit. #### An edit costs about double a generation Every provider bills an edit on the input clip AND the output, so a 20-second edit is priced like 40 seconds of generation. Read the number on the Generate button rather than reasoning from the generation rate. #### When to use it instead of the others Length is the reason: it is the only engine that accepts a clip over 15 seconds. Inside the others' range, choose on fidelity — Omni Flash Edit is the prompt-only fidelity winner and the cheapest seat, and Kling O3 Edit is the one that takes subject and style reference images. #### Prompt and clip only No character or style reference images on this engine. If the edit needs a reference image to lock an identity, that is Kling O3 Edit's job. > 💡 Trim before you edit, not after: the bill is the source clip's length rounded up, so a 30-second clip you only needed 8 seconds of costs nearly four times what it had to. ### Kling 3.0 Kling 3.0 features native audio-visual co-generation with dialogue, sound effects, and music (Omni tier). Define your core subjects clearly at the beginning of the prompt and keep descriptions consistent across shots. #### Dialogue ``` Character says, "exact words here" ``` Use quotation marks for precise speech. Languages (Omni only): English, Chinese, Japanese, Korean, Spanish. #### Voice Quality ``` with a trembling voice, "I'm scared" ``` Describe emotional tone, pitch, or speaking style before the dialogue. No pronouns or synonyms after a character's first introduction — they cause voice drift. #### Sound Effects ``` SFX: heavy boots on wet pavement, distant siren wailing ``` Use the "SFX:" prefix, with physical-cause specificity — "SFX: footsteps" is too vague. #### Multi-Character Dialogue (Omni) ``` Alice says in English, "Hello!" Immediately, Bob replies in Spanish, "¡Hola!" ``` The "Immediately" keyword makes lines back-to-back; without it Kling adds a natural conversational beat. #### Ambient Noise & Music ``` Ambient noise: city traffic, birds chirping Background music: tense orchestral strings ``` Set the background soundscape and request specific music styles or moods. #### Multi-shot ``` Shot 1: ... Shot 2: ... ``` Max 6 cuts, 15s total. One primary action and ONE camera move per shot; describe the subject identically in every shot block. > 💡 Keep dialogue concise (under 10 seconds per line). Use the Language and Accent settings in Audio Controls to control speech characteristics. ### Kling O3 Edit Kling 3.0 features native audio-visual co-generation with dialogue, sound effects, and music (Omni tier). Define your core subjects clearly at the beginning of the prompt and keep descriptions consistent across shots. #### Dialogue ``` Character says, "exact words here" ``` Use quotation marks for precise speech. Languages (Omni only): English, Chinese, Japanese, Korean, Spanish. #### Voice Quality ``` with a trembling voice, "I'm scared" ``` Describe emotional tone, pitch, or speaking style before the dialogue. No pronouns or synonyms after a character's first introduction — they cause voice drift. #### Sound Effects ``` SFX: heavy boots on wet pavement, distant siren wailing ``` Use the "SFX:" prefix, with physical-cause specificity — "SFX: footsteps" is too vague. #### Multi-Character Dialogue (Omni) ``` Alice says in English, "Hello!" Immediately, Bob replies in Spanish, "¡Hola!" ``` The "Immediately" keyword makes lines back-to-back; without it Kling adds a natural conversational beat. #### Ambient Noise & Music ``` Ambient noise: city traffic, birds chirping Background music: tense orchestral strings ``` Set the background soundscape and request specific music styles or moods. #### Multi-shot ``` Shot 1: ... Shot 2: ... ``` Max 6 cuts, 15s total. One primary action and ONE camera move per shot; describe the subject identically in every shot block. #### Video edit — name the change, keep the rest ``` Replace the man in @Video1 with @Element1, keeping his walk cycle, the camera move, and the rain unchanged. ``` > **Critical.** @Video1 is your clip; attached subject refs compile to @Element1..; style refs to @Image1.. (max 4 combined). One edit intent per pass — chain passes for compound changes. Original audio is preserved verbatim. > 💡 Keep dialogue concise (under 10 seconds per line). Use the Language and Accent settings in Audio Controls to control speech characteristics. ### Gemini Omni Flash Gemini Omni Flash is the cheap 720p tier with native synced audio included — dialogue, SFX, and ambient generate WITH the video at no extra cost. 3-10s, 16:9 or 9:16. Text-to-video, one start frame, or up to 7 reference images. No last frame, no video/audio references. #### Structure like a shot brief ``` subject + action + setting + camera + lighting + tone ``` Descriptive prompts are fine for generation (the short-prompt rule is edit-only). #### Dialogue ``` The barista says, "Your usual?" ``` Audio is prompt-driven — there are no audio parameters. Dialogue in quotes. #### Sound in plain language ``` rain patters on the tin roof · distant traffic hum ``` Describe sounds directly in the prose — no SFX: prefix needed. #### Name references inline ``` Marcus (image 1) walks into the cafe... ``` Up to 7 reference images merge into one list — refer to them by number in the prompt. #### Negatives as plain instructions ``` Do not show text. ``` No negative-prompt field — write what to avoid as a direct instruction. #### Know its seat Cheap drafts, iteration volume, and audio-in-one-gen at low cost. For hero shots, Kling 3.0 (general default) or Seedance 2.0 (premium/physics) still win. ### Omni Flash Edit Omni Flash Edit changes what the prompt names in an existing 3-10s clip, footage-synced — prop, effect, environment, and lighting swaps. Prompt + source clip only: no reference images (identity swaps that need refs → Kling O3 Edit). 720p output; voice editing unsupported. #### One short change — MANDATORY ``` Small magical flames appear on his fingertips when he snaps his fingers, and vanish when he blows on them. Keep everything else the same. ``` > **Critical.** Google's own doc: simple prompts work best; overly descriptive prompts cause unintended changes. Long "keep every frame identical" preambles make drift WORSE. One change, then the magic phrase. #### Always end with the preservation phrase ``` ...Keep everything else the same. ``` The one documented preservation lever. Every edit prompt ends with it. #### Never name objects as metaphors ``` ❌ a candle-like flame → ✅ small magical flames on his fingertips ``` "Candle-like" renders a literal candle in his hand. Describe the effect itself. #### No conditional timing cues ``` ❌ ...appears WHEN he calls it, perches AS he walks ``` Beat-by-beat stage directions cued to moments in the footage hard-fail the request. Collapse to one continuous action; the model syncs it to the footage's own motion. #### Frame effects as harmless VFX ``` ❌ his fingertips catch fire → ✅ magical flames appear on his fingertips ``` Google's safety filter is strict about harm-to-person phrasing. Magical/harmless framing passes. #### Expect a possible tail artifact Occasional jitter or a doubled final speech beat in the last ~0.5s. Trim the tail on the timeline — don't burn a re-roll on it. > 💡 Ship via segment-splice: edit only the seconds where the change happens (Trim / Split first), then splice back over the original on the timeline with the original audio underneath. Chain edits one change at a time — each edit saves as a new clip linked to its parent. ### Veo 3.1 Veo 3.1 generates synchronized audio directly with video. Aspect ratio: 16:9 only (for 9:16 vertical, use Kling or Seedance). Native single-clip duration: 4, 6, or 8 seconds — longer durations require chaining clips via last-frame reuse. Official Cloud formula: [Cinematography] + [Subject] + [Action] + [Context] + [Style & Ambiance]. Sweet spot ~50-150 words. #### Dialogue ``` Character says, "exact words" ``` Use quotation marks for exact speech. Keep voice direction terse: "says in a weary voice", "whispers", "shouts". 2-3 speakers max — sync degrades past that. #### Sound Effects — with cause ``` SFX: thunder cracks in the distance ``` Always specify direction or distance — "SFX: thunder" alone is too vague. #### Ambient is mandatory ``` Soft office ambience. · Wind on the open ridge. ``` Include an ambience line in every scene — without it the audio mix feels dead. #### No subtitles — MANDATORY ``` The founder says, "..." (no subtitles). Soft office ambience. ``` > **Critical.** Without (no subtitles) after every dialogue line, Veo bakes subtitle text into the video. This is genuinely critical and underspecified in most guides. #### Cinematography vocabulary ``` 85mm · shallow depth of field · Rembrandt lighting · dolly in · whip pan ``` Veo responds to real lens, lighting, and camera-move terms — lead the prompt with them. > 💡 First-frame + last-frame is Veo's strongest workflow. Generate a start frame, generate an end frame, then animate with both as anchors. Motion-Lock hack: keep ~60% of the same background pixels between start and end to prevent latent drift. > 💡 Keep dialogue under one natural breath — lines fit the 8s clip ceiling. Texture-realism phrases: fine skin pores, visible fabric weave, subtle contrast, no gloss or sharpening. ## Image ### Nano Banana 2 Nano Banana 2 is a language model that outputs pixels. Brief it like a creative director, not like a Stable-Diffusion tag tool. The biggest realism lever: specificity that mimics how real photographers describe their work. Google's 4 official rules: Be specific. Use positive framing (describe what you want, not what you don't). Control the camera with cinematic terms. Iterate conversationally. #### Cinematic prompt formula ``` Film still from [Director] [genre]. Shot on [camera] with [lens]. [Subject + action]. [3-5 details]. [Lighting]. [Color palette]. [Film stock]. ``` Specific gear beats generic descriptors. "ARRI Alexa 65 with Panavision anamorphic" outperforms "cinematic camera." #### Named lenses + apertures ``` 85mm f/1.4 · 135mm f/2.8 · 50mm f/1.2 · 35mm f/2 · Panavision anamorphic · 400mm telephoto ``` 135mm f/2.8 is the cheat code for skin texture and intimate compression. Anamorphic for cinematic width + horizontal flares. #### Named film stocks (one per prompt) ``` Kodak Portra 400 · Fuji Velvia 50 · Ilford HP5 Plus · CineStill 800T ``` Portra = natural skin warmth. Velvia = saturated landscape. HP5 = gritty B&W grain. CineStill 800T = tungsten night with halation. Never mix stocks. #### Don't carry lens + stock into a video prompt ``` 85mm f/1.4, Portra 400 → close-up, shallow depth of field, warm natural colors, cinematic texture ``` Lenses, apertures, film stocks and camera bodies are an image-model lever and a video-model anti-pattern — ByteDance's Seedance guide never mentions f-stops, lens millimetres, fps or shutter angle. When you animate a frame you made here, translate the look into shot size, depth of field and colour tone instead of pasting the gear list across. #### Physics-based lighting ``` Single key light at 45 degrees from upper left. Color temperature 4500K. Crisp catchlights in the eyes. ``` Direction + Kelvin temp + named source. "Single key light at 10 o'clock" beats "soft lighting" every time. #### Imperfection vocabulary ``` visible pores · peach fuzz · ISO noise · sweat beading · slight hyperpigmentation · unretouched raw photography ``` Forces the model away from AI-clean skin. The default is too smooth — you have to ask for the imperfections that real photos have. #### ❌ The anti-list — avoid these ``` 8k · masterpiece · hyperrealistic · ultra-detailed · trending on ArtStation · perfect skin · flawless · airbrushed · cinematic (alone) ``` > **Critical.** Tag-soup phrases from the Stable-Diffusion era. Measured success ~60-70% with these vs ~95%+ with positive description. Always specify which cinema — director, lens, era, stock. #### No negative-prompt field ``` ✅ "empty street" not "no cars" ✅ "without people, vehicles, or signage" ❌ "not anime, not cartoon, not 3D" ``` Reframe positively first. Use inline "without" / "free of" only when positive framing can't suppress the unwanted element. #### Reference images — name them, never label roles ``` Marcus (image 1) sits across from the woman (image 2) in the cafe (image 3). ``` Up to 14 refs (10 object + 4 character — caps don't trade). Name each reference inline; never write role essays. Slates does this for you: `@mention` a subject or environment and it composes `Marcus (image 1) in the cafe (image 2)`, citing them in the exact order it sends them. One canonical identity image avoids competing facial renderings; a "Reference Image Instructions" block drags reference lighting into your scene. Start with 2-3 focused refs. #### Common fixes ``` Hands → "five fingers, natural proportions" Text → quote-wrap "HEADLINE" + specify font Left/right → "from the character's perspective" ``` Default left/right is the viewer's perspective. Surreal prompts trip uncanny valley — the model drags toward realism. For surrealism, lean hard into "painted" / "illustrated". #### Resolution tactics ``` 1k = drafts · 2k = hero · 4k = print/final ``` Pick by need. 2K+ allocates more tokens to surface detail, so texture vocab (pores, fabric weave, grain) compounds at higher resolution. > 💡 Boring vs Cinema. Boring: "Wide shot of man on dock looking at forest." Cinema: "Direct overhead drone shot on weathered dock. Single figure climbing up frame bottom. Boot prints leading toward shore. Pale winter light. Anamorphic flare. Desaturated blue/slate palette. Kodak Portra 400 grain. Map of threat." > 💡 3-strike rule. If three iterations on the same prompt haven't landed, stop. The slot machine doesn't converge — the prompt structure is wrong, not the seed. ### Nano Banana 2 Lite Nano Banana 2 is a language model that outputs pixels.

"Single key light at 10 o'clock" beats "soft lighting" every time. #### Imperfection vocabulary ``` visible pores · peach fuzz · ISO noise · sweat beading · slight hyperpigmentation · unretouched raw photography ``` Forces the model away from AI-clean skin. The default is too smooth — you have to ask for the imperfections that real photos have. #### ❌ The anti-list — avoid these ``` 8k · masterpiece · hyperrealistic · ultra-detailed · trending on ArtStation · perfect skin · flawless · airbrushed · cinematic (alone) ``` > **Critical.** Tag-soup phrases from the Stable-Diffusion era. Measured success ~60-70% with these vs ~95%+ with positive description. Always specify which cinema — director, lens, era, stock. #### No negative-prompt field ``` ✅ "empty street" not "no cars" ✅ "without people, vehicles, or signage" ❌ "not anime, not cartoon, not 3D" ``` Reframe positively first. Use inline "without" / "free of" only when positive framing can't suppress the unwanted element. #### Reference images — name them, never label roles ``` Marcus (image 1) sits across from the woman (image 2) in the cafe (image 3). ``` Up to 14 refs (10 object + 4 character — caps don't trade). Name each reference inline; never write role essays. Slates does this for you: `@mention` a subject or environment and it composes `Marcus (image 1) in the cafe (image 2)`, citing them in the exact order it sends them. One canonical identity image avoids competing facial renderings; a "Reference Image Instructions" block drags reference lighting into your scene. Start with 2-3 focused refs. #### Common fixes ``` Hands → "five fingers, natural proportions" Text → quote-wrap "HEADLINE" + specify font Left/right → "from the character's perspective" ``` Default left/right is the viewer's perspective. Surreal prompts trip uncanny valley — the model drags toward realism. For surrealism, lean hard into "painted" / "illustrated". #### Resolution tactics ``` 1k only on Lite ``` Lite outputs 1K only — use it for iteration volume and drafts, then switch to Nano Banana 2 for 2K/4K finals. > 💡 Boring vs Cinema. Boring: "Wide shot of man on dock looking at forest." Cinema: "Direct overhead drone shot on weathered dock. Single figure climbing up frame bottom. Boot prints leading toward shore. Pale winter light. Anamorphic flare. Desaturated blue/slate palette. Kodak Portra 400 grain. Map of threat." > 💡 3-strike rule. If three iterations on the same prompt haven't landed, stop. The slot machine doesn't converge — the prompt structure is wrong, not the seed. ## Audio ### Seed Audio 1.0 Seed Audio builds a whole audio scene — dialogue, effects and ambience together — from one plain sentence. Write it the way you would describe the moment to a person standing next to you, not the way you would write a video prompt. It has no duration setting. Length comes from the words, so Slates appends your chosen duration to the prompt ("… 15 seconds") and bills exactly that. Set the duration control to what you actually want and let the sentence stay clean. #### One plain sentence ``` nature soundscape, wide open field cicadas and birds and a loon. ``` No shot language, no production jargon, no formatting. Plain description outperforms anything that reads like a spec sheet. #### Duration lives in the prompt ``` tiny applause of 2 or 3 people at an open mic. 15 seconds ``` > **Critical.** The duration control writes this for you. Do not also type a different length into your sentence — the two will fight and you pay for the one you selected. #### Say the crowd size ``` tiny applause of 2 or 3 people · a packed arena roaring ``` "Applause" alone returns a full room. Scale words are the single highest-leverage edit on any crowd, traffic or nature bed. #### Cut beds longer than the shot Ask for a few seconds more than the clip needs so the edit has handles to fade in and out of. Beds that end exactly on the cut always sound clipped. #### No Kling syntax here ``` ✗ SFX: heavy boots ✓ heavy boots on wet pavement, a siren far off ``` > **Critical.** The "SFX:" and "Ambient noise:" prefixes belong to Kling video prompts. Seed Audio treats them as words in the scene and the result gets worse. #### Dialogue in quotes ``` a tired bartender says, "we closed twenty minutes ago", glasses clinking behind him ``` Speech goes in quotes inside the same sentence as the room. Pick a preset voice for a specific speaker, or leave it unset and let the scene cast itself. #### References ``` match the room tone of @Audio1 ``` Up to 3 audio clips (max 30s each), referenced as @Audio1–@Audio3 — OR one image to score what is in frame. Never both in the same generation. #### Know its seat Scenes, beds, room tone and dialogue in one pass. For a single effect that has to land on a specific frame, use Sound Effects. ### ElevenLabs Sound Effects Sound Effects makes one short sound with an exact length — the lane for a hit that has to land on a specific frame, or a seamless loop you can lay under a whole scene. Duration is always sent explicitly (0.5–22s). Billing is per second, so the length you pick is the price you pay. #### Describe the cause, not the label ``` ✗ door sound ✓ heavy oak door slams shut in a stone hallway ``` > **Critical.** Material, weight and room are what separate a usable effect from a stock-library shrug. Name all three. #### One sound per generation This surface makes a single event. A door, then footsteps, then a siren is three generations layered on the timeline — or one Seed Audio scene. #### Duration is the edit ``` 0.8s for an impact · 4s for a whoosh · 22s for a bed ``` Ask for roughly the length you need. A 4-second request for a door slam pads the tail with room tone you then have to trim. #### Loops ``` steady rain on a canvas tent (loop on, 12s) ``` Turn loop on for anything continuous — rain, engine hum, crowd murmur — and it will tile without a seam. #### Prompt influence ``` 0.3 default · 0.7 literal ``` Higher hugs your wording with less variation between takes; lower explores. Raise it when a re-roll keeps wandering off the brief. #### Know its seat One precise effect on a known frame. Full rooms and layered scenes are cheaper and better in one Seed Audio pass. ## Going deeper The tips above are the short version. The full prompting craft ships as the Slates skills library with the community membership: per-model long-form guides, character identity, style prompting, cost discipline, the vision feedback loop and campaign blueprints.

You watch the desktop app fill in live as the agent works. Works with **Claude Code**, **Claude Desktop**, **Cursor**, **Codex**, and any MCP-capable client. > You need the **Slates desktop app** installed and open — the agent talks to a local server it runs. [Download Slates](https://slates.video/download) first if you haven't. ## Let your AI set it up If you already have Claude, Cursor, or Codex open, hand it the job. Copy the block below, paste it into a new chat, and let it wire everything up. ``` Set up the Slates MCP server for me. Slates is a desktop app for AI video creation. It exposes an MCP server so you can drive it for me: create projects, generate images and video, build characters and storyboards, assemble the editing timeline, and export a finished MP4. Please do the following, in order. 1. Work out which MCP client you are running inside: Claude Code, Claude Desktop, Cursor, or Codex. If you cannot tell, ask me. 2. Register the Slates MCP server with that client. Claude Code: claude mcp add slates -- npx -y @slatesvideo/mcp-server Codex: codex mcp add slates -- npx -y @slatesvideo/mcp-server Claude Desktop or Cursor: add this block to the client's MCP config file, creating the file if it does not exist. { "mcpServers": { "slates": { "command": "npx", "args": ["-y", "@slatesvideo/mcp-server"] } } } This needs Node.js 18 or newer. If npx is missing, tell me to install Node first and stop. 3. Stop and hand this step back to me, because you cannot do it yourself. Tell me to: open the Slates desktop app, go to Settings, then Agent Control, enter my account email, click Send link, and click the link in the email. That one step authorizes the connection and starts the local server that you will be talking to. It writes a connection file at ~/.slates/agent-connection.json which both the CLI and the MCP server find on their own. There are no API keys and no environment variables to set. 4. After I confirm I have done step 3, tell me to fully restart this client so it picks up the new server. 5. Once restarted, verify it actually works: list the Slates tools you can see, then call the tool that lists my projects and show me the result. Do not tell me setup is complete until a real tool call has returned. If anything fails, show me the exact error rather than working around it. Reference: https://slates.video/docs/connect-claude ``` It will stop and ask you to do one step yourself: authorizing the connection from inside Slates. That step needs a link from your email, so no agent can do it for you. ## The easy way (no terminal) 1. Open Slates → **Settings → Agent Control**. 2. Enter your account email and click **Send link**, then click the link in your email. This authorizes the agent _and_ starts the local server in one step. 3. Under **Connect your AI tool**, click **Connect** next to Claude Desktop, Claude Code, or Cursor — Slates writes that tool's MCP config for you. 4. Restart your AI tool. Slates appears in its tools. That's it. No JSON editing, no API keys to paste. ## From a terminal One command wires the MCP config into every detected client, installs the agent skills, and points you at the connect step: ```bash npx -y @slatesvideo/cli setup ``` Then connect your account (Slates → Settings → Agent Control → Send link, or `slates login`) and restart your AI tool. ### Claude Code ```bash claude mcp add slates -- npx -y @slatesvideo/mcp-server ``` ### Codex ```bash codex mcp add slates -- npx -y @slatesvideo/mcp-server ``` ### Claude Desktop / Cursor Add the MCP server to your client config: ```json { "mcpServers": { "slates": { "command": "npx", "args": ["-y", "@slatesvideo/mcp-server"] } } } ``` Or grab the one-click **`.mcpb` bundle** for Claude Desktop from the [latest release](https://github.com/EricDisero/slates-mcp/releases/latest) and double-click to install. ## Packages - [`@slatesvideo/cli`](https://www.npmjs.com/package/@slatesvideo/cli) — the `slates` command (`setup`, `login`, `run`, `install-skills`, `mcp`). - [`@slatesvideo/mcp-server`](https://www.npmjs.com/package/@slatesvideo/mcp-server) — the MCP server (`npx -y @slatesvideo/mcp-server`). - [Source on GitHub](https://github.com/EricDisero/slates-mcp). Both surfaces share one config file (`~/.slates/agent-connection.json`) that the desktop app and the CLI auto-discover — no environment variables. --- # Agentic Skills Pack setup Source page: https://slates.video/docs/skills-pack # Agentic Skills Pack — setup The Agentic Skills Pack is a set of ready-to-run **agentic workflows and prompting skills** — the exact ones we use to make our own videos. Your AI agent (Claude Code, Claude Desktop, Cursor, or any MCP client) reads them and drives Slates for you: faceless YouTube videos, UGC ads, product demos, batch B-roll, and more, hands-off. > **Before you start:** the pack rides on the Slates agent connection. If your AI tool isn't wired to Slates yet, do [Connect Claude & AI agents](https://slates.video/docs/connect-claude) first — it takes about two minutes. ## 1. Download and unzip Your download link is in your **welcome email** (it stays live forever — grab it again anytime, from any device). Unzip the pack anywhere you like. Inside you'll find: - `README.md` — the same instructions as this page, offline - `skills/` — one ready-to-use folder per skill (`/SKILL.md`): the production workflows (one-prompt film, direct-response ad, storyboard-from-script, character turnaround, edit-and-iterate, vision feedback loop) plus per-model prompting mastery and the craft/discipline skills ## 2. Install the skills ### One command (recommended) From any terminal: ```bash npx -y @slatesvideo/cli install-skills --global ``` That installs every skill for Claude Code account-wide (drop `--global` to install into just the current project). Done. ### No terminal? Copy the folders Each skill in `skills/` is a ready-to-use folder. Copy the ones you want into: - **Claude Code (this project):** `.claude/skills/` inside your project folder - **Claude Code (everywhere):** `~/.claude/skills/` — on Windows that's `C:\Users\\.claude\skills\` - **Claude Desktop / Cursor / other MCP clients:** the skills also work as plain instructions — open any `SKILL.md` and paste its contents into your conversation (or your tool's rules/custom-instructions area) when you want that workflow Restart your AI tool after installing — skills load at startup. ## 3. Use them Open your AI tool and just ask. The skills trigger automatically when the request matches — you don't invoke them by name: > "Make me a 30-second UGC-style ad for my coffee brand in Slates." > "Build a faceless YouTube video from this script — storyboard it, generate the shots, and assemble the timeline." The agent will open a Slates project, generate the assets, and assemble everything while you watch the app fill in live. ## Troubleshooting - **The agent doesn't see Slates at all** → your MCP connection isn't set up. Do [Connect Claude & AI agents](https://slates.video/docs/connect-claude), then restart the AI tool. - **Skills don't trigger** → make sure the skill folders (not the zip) are in the skills directory, and restart your AI tool. Skills load at startup. - **Generations fail with a credit error** → check your balance in the Slates top bar. Every generation shows its credit price before it runs. - **Anything else** → jump in the [Discord](https://discord.gg/d9qnuM2rjv) or email [hello@slates.video](mailto:hello@slates.video) — we'll get you running.
