Creative Claw

Delete a brand theme (soft-delete). If the deleted theme was the default, the oldest remaining theme is promoted.

delete_theme

Extract frames from a video as images. Returns permanent URLs to the extracted frame(s). Modes: - **single**: Extract one frame — first, middle, or last. Great for thumbnails. - **batch**: Extract every Nth frame from the video. Great for storyboards or frame-by-frame analysis. Tips: - Use single mode with position="middle" for a representative thumbnail - For batch mode, frame_interval=12 at 24fps gives roughly 2 frames per second - Lower frame_interval = more frames extracted (higher cost) - Use max_frames to cap the number of extracted frames

extract_frames

Generate or edit images using AI models. **Two modes:** - **Generate** (no image_url): Create an image from a text prompt. - **Edit** (with image_url): Transform an existing image based on the prompt. The result renders automatically in an inline widget that polls for completion on its own — the user sees the image without any further action from you. Do NOT call check_job just to display or confirm the result; that only adds redundant round-trips. Call check_job ONLY when YOU need the final image URL for a follow-up step (editing it, reusing it as a reference, saving, or posting it). Recommended models (pass as the "model" parameter). Prefer Google Nano Banana 2 — it's the top pick for almost everything: - "image/nano-banana-2" — Google Gemini 3.1 Flash Image. ⭐ DEFAULT & TOP PICK — best all-around balance of quality, intelligence, speed, and cost [generate + edit] - "image/nano-banana-pro" — Google Gemini 3 Pro Image. Best for complex professional assets, precise multilingual typography, multi-reference compositions, and demanding edits [generate + edit] - "image/seedream-5-pro" — ByteDance Seedream 5 Pro via Pika. Flagship product/marketing generation and precise edits using up to 10 references; 1K/2K output [generate + edit] - "image/gpt-image-2" — OpenAI GPT Image 2. Strong instruction following, text rendering, transparency, and precise editing [generate + edit] Default to image/nano-banana-2 as the cost-efficient choice for most work. Escalate to image/nano-banana-pro for complex professional assets or demanding typography, image/gpt-image-2 for instruction-heavy generation and precise edits, or image/seedream-5-pro for premium commercial imagery. Use list_models to discover other available models only when the user asks or the brief requires a capability these four do not cover. Use get_model_params with the selected model ID before passing model-specific parameters. Tips: - Use the `size` field for output dimensions. Supported values: "1:1" (1080x1080), "4:5" (1080x1350, IG portrait), "5:4" (1350x1080), "9:16" (1080x1920, story/reel), "16:9" (1920x1080, wide). These are normalized for the recommended image models. - In ChatGPT, call import_chatgpt_media for files already pasted, attached, or generated in the conversation. Call import_media only when the user needs the interactive upload picker. Use the durable Creative Claw URL returned by either tool. - width/height are still accepted for backwards compatibility but `size` is preferred — different models silently disagree on which dimension param they read, and `size` normalizes for you. - Set seed for reproducible results - For editing, strength controls how much to change: 0.0 = barely alter, 1.0 = completely reimagine (default 0.75) - Models marked [edit only] require image_url. Models marked [generate only] cannot edit. - Use get_model_params to discover model-specific parameters, then pass them via the "extras" field - extras.image_urls provides additional style/character reference images — NOT for compositing. Every URL must be public/directly fetchable or returned by import_media/import_chatgpt_media. The source image should always be passed via image_url. If you pass extras.image_urls without image_url, the first URL is automatically used as the source image. - GPT Image 2 rejects individual reference files larger than 25 MB. Compress oversized references or use a Nano Banana model, which may accept the same Creative Claw URLs.

generate_image

Generate speech audio from text using AI text-to-speech models. Returns a permanent audio URL with an inline audio player. Recommended TTS models (pass as the "model" parameter). Prefer ElevenLabs v3 — it's the top pick for almost everything: - "speech/elevenlabs-v3" — ElevenLabs v3. ⭐ DEFAULT & top pick — industry-leading naturalness, inline [audio tags] for emotion/delivery, voice cloning, 70+ languages. Use this unless there's a specific reason not to. Full guide: creative-claw://guides/speech/elevenlabs-v3 Default to speech/elevenlabs-v3 for narration, dialogue, multilingual speech, and expressive delivery. Use list_models to discover alternatives only when the user requests one or ElevenLabs cannot satisfy a required capability. Use get_model_params with the selected model ID before passing advanced settings. Tips: - ElevenLabs v3 (speech/elevenlabs-v3, the default) is the recommended model. Get the most out of it: - Inline [audio tags] shape delivery — drop them anywhere in the text and they're performed, not spoken. Emotion: [excited], [sad], [angry], [sarcastically], [curious], [nervous], [whispers], [shouting]. Non-verbal: [laughs], [chuckles], [sighs], [gasps], [clears throat], [coughs]. Pacing: [slowly], [fast-paced], [pause], [drawn out]. Accent/voice morph: [strong French accent], [pirate voice], [robotic tone]. Use 1 tag per 1–3 sentences — overuse flattens the effect; don't stack tags ([whispers][angry]); stick to known tags (made-up ones are ignored). - Pick a voice_id matching the brief from the curated list (see voice_id param). Omitting it gives Hale (confident American male). For multi-speaker dialogue, make one call per line with a distinct voice_id per character. - Tune delivery with extras: { voice_settings: { stability, similarity_boost, speed } } — stability 0.3 (Creative, most expressive, best for tags), 0.5 (Natural, default), 0.8 (Robust, may ignore tags). e.g. energetic ad: { stability: 0.3, similarity_boost: 0.7, speed: 1.05 }; calm narration: { stability: 0.5, speed: 0.95 }. - Keep each call under ~3000 chars; chunk long scripts on sentence boundaries and merge the resulting audio clips. Per-word timestamps are requested automatically (returned in structuredContent) for captions/lip-sync. - Full reference (voice table, tag vocabulary, dialogue & long-form recipes): resource creative-claw://guides/speech/elevenlabs-v3 - For multi-speaker dialogue in a single call, use Dia TTS (speech/dia-tts) with [S1]/[S2] speaker tags and cues like (laughs) - For expressive speech, use Orpheus TTS with tags like <laugh>, <sigh>, <gasp> - For xAI TTS (speech/xai-tts), voice_id is mapped to fal's voice field. Current voices include eve/ara/rex/sal/leo plus the expanded catalog in the model guide. Insert inline cues anywhere in the text — [laugh], [chuckle], [sigh], [breath], [pause], [whisper]. For phone-call/IVR audio pass format: "mulaw" and sample_rate: "8000". Force a language with extras: { language: "es-ES" } (default is auto). See resource creative-claw://guides/speech/xai-tts for the full reference. - For voice cloning with Chatterbox, pass audio_url pointing to a reference audio sample (public mp3/wav). Never send ElevenLabs [bracketed] tags to Chatterbox; use only its supported angle tags: <laugh>, <chuckle>, <sigh>, <cough>, <sniffle>, <groan>, <yawn>, <gasp>. Known incompatible tags are sanitized server-side. - Use speed to control speech rate (0.5 = half speed, 2.0 = double speed) - Use emotion to set the overall tone (MiniMax models; ElevenLabs uses inline [audio tags] instead) - Use get_model_params with any model ID (e.g. speech/elevenlabs-v3) for the full parameter list

generate_speech

Submit a video generation job using AI models. Returns a job ID immediately — video generation runs in the background (typically 30s–2min). The result renders automatically in an inline widget that polls for completion on its own — the user sees the video without any further action from you. Do NOT call check_job just to show or confirm the video. Call check_job ONLY when YOU need the final video URL for a follow-up step. Recommended models (pass as the "model" parameter). Prefer Google Gemini Omni 1.1 Flash — it's the top pick for almost everything: - "video/gemini-omni-flash" — Google Gemini Omni 1.1 Flash. ⭐ DEFAULT & TOP PICK — generally available multimodal video with native audio; turns text, images, reference images, or a source video into a new/edited clip [text + image + reference + edit] - "video/minimax-h3-max" — MiniMax H3 Max via fal. Fast 5–15s native-audio video at 480P/768P with strong prompt adherence, optional first/last frames, and up to 12 image/video/audio references using Image 1 / Video 1 / Audio 1 syntax [text + image + reference-to-video] - "video/minimax-h3-max-turbo" — MiniMax H3 Max Fast. Faster, lower-cost H3 Max route for quick text or image-to-video iteration [text + image] - "video/seedance-2.5" — Seedance 2.5 (ByteDance). Premium native-audio generation, 4–30s at 480p–1080p, optional first/last frames, and up to 50 multimodal references (30 images, 10 videos, 10 audio clips) [text + image + reference-to-video] - "video/seedance-2.0-mini" — Seedance Mini. Economical native-audio drafts with multimodal references at 480p/720p [text + image + reference-to-video] Default to video/gemini-omni-flash unless the request specifically calls for another model's specialty. Use Seedance 2.5 for premium long or reference-rich work, Seedance Mini for economical drafts, MiniMax H3 Max for fast cinematic native-audio clips, or H3 Max Fast when iteration speed matters most. Provide image_url to generate video from an image — the model's image-to-video endpoint is used automatically. Use list_models to discover other available models only when the user asks or the task requires a capability these recommendations do not cover. Use get_model_params with the selected model ID to see current parameters and reference limits. Tips: - Provide image_url to generate video from an image — the correct endpoint is selected automatically - In ChatGPT, call import_chatgpt_media for files already pasted, attached, or generated in the conversation. Call import_media only when the user needs the interactive upload picker. Use the durable Creative Claw URL returned by either tool. - Provide both image_url + last_frame_url to generate a video transitioning between two frames (Veo 3.1, Kling v3 Pro, MiniMax H3 Max, and MiniMax H3) - Provide image_urls/video_urls/audio_urls only within the selected model's current limits. Seedance uses @Image1/@Video1/@Audio1; H3 Max references are normalized automatically to fal's Image 1/Video 1/Audio 1 syntax (or Pika's @ tokens where available) - For FLUX 3 extension, set model to video/flux-3, operation to extend, and pass the source clip as video_urls[0]. Other retake/extend/reframe calls use LTX 2.3 Fast - Set operation to audio_to_video with audio_urls[0], plus either image_url or a prompt; LTX 2.3 Fast is selected automatically - Set operation to animate_character with image_url (or character_id) and the driving performance in video_urls[0]; DreamActor v2 is selected automatically - Duration is model-dependent: Seedance 2.5 accepts integer strings "4" through "30"; Seedance Mini and H3 Max accept whole seconds in their current supported ranges. Use get_model_params for the exact selected model before generation - Resolution is model-dependent: pass the top-level resolution parameter using a value from get_model_params. MiniMax H3 Max defaults to 768P and also supports 480P; standard H3 defaults to 768P and supports 2K - When animating a still image, explicitly request visible subject and environmental motion. Review the completed clip before describing it as animated; camera movement over a static subject may not satisfy the request. - Use get_model_params to discover model-specific parameters, then pass them via the "extras" field

generate_video

Load a film project and show its preview (cast, script, shots, assembled cut).

get_film_project

Get all available input parameters for a specific AI model. Returns the full schema including parameter names, types, defaults, constraints, and descriptions. Use this to discover model-specific parameters before generation. Many models support custom params beyond the standard ones (prompt, width, height, seed, etc.). Pass discovered params via the "extras" field in generate_image, generate_video, or generate_speech. Example workflow: 1. list_models → find a model 2. get_model_params → see all its parameters 3. generate_image with extras: { "enable_safety_checker": false, "sync_mode": true } This is especially useful for: - Discovering model-specific features (LoRA weights, schedulers, safety toggles, image_size presets, etc.) - Finding the exact parameter names and valid values a model expects - Understanding which parameters are required vs optional

get_model_params

Fetch a brand theme. Themes are reusable brand configuration bundles (colors, fonts, logos, product images, etc.) stored as JSON — use them to keep generated media on-brand. Returns the theme's name, default status, and full data. Omit name to get the default theme.

get_theme

Get a presigned URL for uploading file bytes directly to storage. Use this when the client can read a local file and make the PUT request itself, especially Codex and other local execution environments. Also use it for files too large for URL-based import (>37MB). Do NOT use this for a file already pasted, attached, or generated in a ChatGPT conversation. Use import_chatgpt_media for an existing ChatGPT file, or import_media when the user still needs the interactive picker. Returns a temporary upload URL (valid for 1 hour) and an asset ID. After uploading the file, call confirm_upload with the asset ID to finalize. Workflow: 1. Call get_upload_url to get the upload URL and asset ID 2. Upload the file: curl -X PUT -H "Content-Type: video/mp4" -T /path/to/file.mp4 "<uploadUrl>" 3. Call confirm_upload with the asset ID to verify and activate the asset Example: get_upload_url({ content_type: "video/mp4", type: "video", name: "my-video" })

get_upload_url

Copy one image, video, or audio file attached to or generated in ChatGPT into Creative Claw storage. Call this before using a native ChatGPT file with Creative Claw generation or editing tools. It returns a durable Creative Claw URL usable as image_url, media_url, audio_url, or video_url. If the media already has a publicly reachable URL, pass that URL directly to the destination tool instead.

import_chatgpt_media

Open an interactive upload UI for the user to choose images, videos, audio, or fonts from their device. Call this tool when: - The user has local files and wants to choose them through the Creative Claw picker - The user wants to browse for or upload one or more files through the Creative Claw picker - The user wants to upload a reference image for editing or video generation - The user asks to upload or import media files from their device After the user uploads files through the UI, their permanent URLs will be provided. You can then use those URLs with generate_image, generate_video, remove_background, upscale_media, etc. ChatGPT: if the file is already pasted, attached, or generated in the conversation, do not open this picker. Call import_chatgpt_media with that native ChatGPT file instead.

import_media

Clean up an audio file using ElevenLabs Voice Isolator — removes background noise, music, and reverb so only the voice remains. **Workflow:** in ChatGPT, call `import_chatgpt_media` for an audio file already attached or pasted; call `import_media` only to open the upload picker. Then pass the durable URL here. Returns a job ID — poll `check_job` until status="completed" to get the cleaned audio URL. **Supported formats:** mp3, wav, m4a, ogg, aac. **Pricing:** 80 credits flat per call, sized from current fal pricing and recent production usage.

isolate_audio

List all Characters (reusable personas). Returns each character's id, title, description, whether it has a cloned voice, and its reference image. Pass a character's id as character_id to generate_image / generate_video / generate_speech. The MCP client renders results as a thumbnail carousel — click a card to copy the character ID.

list_characters

List your film projects (newest first). Click a card to copy its id.

list_film_projects

List available AI models, filtered by category or search query. Categories: - "image" — models that generate and/or edit images - "video" — models that generate video from text and/or images - "speech" — text-to-speech models Each model shows its capabilities in brackets: [generate], [edit], [image-to-video]. The returned model ID is what you pass as the "model" parameter to generate_image, generate_video, or generate_speech.

list_models

List the caller's reusable image templates. Use this to discover templates by name before calling render_template, e.g. "generate a LinkedIn card announcing X" → list_templates → find the LinkedIn one → render_template with the matching ID or name. By default each result is lean — id, name, description, and dimensions — so listing many templates stays cheap. Set include_html=true to also return each template's full HTML, parameter schema, and static-asset list (token + url). Use this when you want to inspect or tweak a template before re-saving it via update_template; otherwise leave it off. Names are case-insensitive and unique per user, so you can pass either the id or the name to render_template. The MCP client renders results as a thumbnail carousel — click a card to copy the template name (or tap the small ID pill to copy the UUID instead).

list_templates

List all brand themes. Returns each theme's name, default status, and a summary of stored keys (colors, fonts, logos, etc.). The MCP client renders results as a thumbnail carousel — click a card to copy the theme name (or tap the small ID pill to copy the UUID instead).

list_themes

Load an image from a URL and return it as base64 so you can see it in your context. Use this ONLY when: - The user explicitly asks you to look at / review an image - You need to iterate on a generated image (view it before deciding on edits) - You need to compare before/after versions of an image Do NOT call this automatically after every generate_image call — only when you or the user actually need to see the image to make decisions. The URL alone is usually sufficient to share with the user.

load_image

Create or update a Character — a reusable persona with a description and reference image. **To create a character:** 1. Collect name + description (appearance, personality, role) 2. Generate a reference image with generate_image using this prompt template (agentic_prompting: false): "Character reference sheet for [name]: [description]. Four views on a plain white background — front, 3/4 view, side profile, back — same pose, consistent lighting. Full body, head to toe. Clean studio style. No text or labels." 3. Call manage_character({ title, description, image_url }) **To add or replace a cloned voice:** After the Character exists, use the dedicated clone_voice tool with the Character id, a public audio sample URL, and explicit consent. **To update any field on an existing character:** Pass id + any fields to change (title, description, or image_url).

manage_character

Queue a media merge and return a job ID immediately. The merge runs in the background; call check_job with the returned job ID when you need the permanent output URL. Operations: - **merge_audio_video**: Combine a video with an audio track (e.g., add narration or music to a video). Provide video_url and audio_url. - **merge_videos**: Concatenate multiple videos back-to-back in order. Provide video_urls array. - **merge_audios**: Concatenate multiple audio files in order. Provide audio_urls array. Common workflow: generate a video with generate_video, generate narration with generate_speech, then merge them with merge_audio_video. Tips: - For merge_audio_video, if the audio is longer than the video (or vice versa), the output length matches the shorter one - Videos being merged should ideally have the same resolution and codec for best results - Use scale_video/trim_video to adjust videos before merging if needed

merge_media

Remove the background from an image or video using AI. Returns a permanent URL to the result. - For **images**: produces a transparent PNG. Just provide the URL and type=image. - For **videos**: uses BEN v2 AI segmentation with temporal consistency. Supports webm (true alpha) or mp4 output. Video background removal costs 120 credits. Tips: - For videos, webm gives true transparency. mp4 produces black background unless composited.

remove_background

Display live, interactive HTML directly in the viewer — no screenshot, no image generation, no credits. Tailwind CSS is automatically included, so use utility classes freely. The HTML is rendered in a sandboxed iframe with full CSS support. Use this when you want to **show** something visual to the user rather than generate a static image: - Brand identity boards (colors, typography, logo layouts) - Asset galleries and comparison layouts - Styled previews (quote cards, social posts, landing page mockups) - Data visualizations and dashboards - Any custom HTML presentation Tailwind CSS is injected automatically — just use classes like "flex items-center gap-4 bg-blue-500 text-white rounded-xl p-6". Custom <style> blocks also work for anything beyond Tailwind. For static PNG output (e.g. social cards, OG images), use render_html_image instead.

render_html

Render HTML/CSS to a PNG image via headless Chromium. Great for branded graphics (social cards, banners, OG images) — faster and cheaper than generate_image for layout-driven content. **Tailwind CSS:** All Tailwind utility classes work out of the box — no CDN script or stylesheet needed. Just use classes like bg-blue-500, text-white, flex, rounded-xl, shadow-lg directly in your HTML. **Full CSS surface:** flexbox, grid, filter (blur, grayscale, hue-rotate, drop-shadow), mask-image, object-fit, transform, gradients, <style> blocks, class selectors, pseudo-elements, variable fonts (all weights 100-900 + italic). Write HTML like you would for a real browser. **Fonts:** Any web font works — this is a real browser. Load fonts directly in the HTML: `<link rel="stylesheet" href="...">`, `@import url(...)`, or `@font-face`. Works with Google Fonts, Bunny Fonts, Adobe Fonts, your own CDN, etc. For a custom/local font, pass it via inline_images and reference it from `@font-face { src: url('{{my_font}}') format('woff2'); }`. The renderer waits on `document.fonts.ready` before screenshotting, so whatever the page declares is what gets rendered. No default font is injected — be explicit. **Typical cold-render time:** ~1-3s (first render pays the browser cold-start; subsequent renders reuse the browser and complete in ~700ms-1.5s). Concurrency is capped server-side. For reusable layouts, use create_template + render_template instead.

render_html_image

Render an HTML/CSS/JS composition to an MP4 video using HyperFrames on Modal.com. **This tool is asynchronous.** It returns immediately with a `jobId` and `status: "queued"`. Rendering typically takes 30–120 s depending on duration and fps. Call `check_job` with the returned `jobId` to poll for completion. Animate elements using GSAP, CSS transitions, or HyperFrames data-* timing attributes. Tailwind CSS works out of the box. Web fonts work via @font-face, @import, or a <link> tag. For audio, add a timed `<audio id="..." src="https://..." data-start="0" data-duration="...">` element. Use an absolute HTTP(S) URL. Inline base64/data/blob URLs, relative paths, and `<source>`-only audio are unsupported. If authored audio is missing or digitally silent in the encoded file, the render fails and is refunded instead of returning a silent video. Common sizes: 1920×1080 (16:9), 1080×1920 (9:16 vertical), 1080×1080 (square). Costs 5 credits per render, independent of duration, fps, and dimensions. A renderer failure, encoded-file dimension mismatch, or authored-audio validation failure is refunded automatically.

render_html_video

Render a saved template one or more times with different parameter values. Returns PNG images. **Multi-variant rendering (the common case):** pass `renders` as an array — each entry is the per-variant modifications. Great for "give me 3 versions of this card with different headlines" or "render this template for X, Y, Z". Up to 4 variants per call. All variants share the same template and size; only `modifications` differs per variant. Charged 4× for 4 variants etc. **Single render:** pass `renders` as a 1-element array. **Looking up the template:** pass either template_id (UUID) or template_name (case-insensitive). If you don't know which template to use, call list_templates first. **How modifications work:** - Pass values keyed by parameter name, e.g. { headline: "Launch day!", hero_image: "https://..." } - Missing parameters fall back to their defaults. Required parameters with no default and no value error out. - Text values are HTML-escaped. image_url values are fetched server-side and inlined as data URIs. - Static assets defined on the template (logos, etc.) are always included. **Failure semantics:** all-or-nothing credit charge. If any variant fails to render, the entire credit charge is refunded. Successful variants are still returned so you can see what worked.

render_template

Resize a video to target dimensions. Returns a permanent URL to the scaled video. Great for reformatting video for different platforms (e.g. 16:9 → 9:16 for Reels/TikTok). Tips: - Provide just width or just height to maintain aspect ratio. - Width and height must be even numbers. - Use mode=pad for letterboxing, mode=crop for center-crop.

scale_video

Search your media library. Assets are images, videos, audio, and 3D models that were generated, uploaded, or imported — each has a permanent URL, optional name, tags, and description. Filter by type, text query (matches name/description/prompt), tags, name, or source. Results ordered newest-first. Examples: search_assets({}) → recent assets. search_assets({ type: "image", query: "sunset" }) → matching images. search_assets({ tags: ["brand"] }) → tagged assets.

search_assets

Report product feedback about Creative Claw — bugs, missing capabilities, confusing flows, or praise. Use this when the user asks to report feedback. You may also suggest it when you observe meaningful product friction, but do not send until the user approves: - The user wanted something no tool can do → category 'missing_feature'. - A tool errored, returned wrong/poor output, or you had to retry/work around it → 'bug'. - A tool, parameter, or its output was confusing or hard to use → 'confusing'. Set source='agent' for the above — you are reporting what you observed. Also use it to relay the user's OWN feedback (quote them) → source='user'. If the user expresses a wish, complaint, or compliment about the app, capture it here. It returns a short acknowledgement, does NOT cost credits, and never blocks the media workflow. One concise, specific report beats several vague ones.

submit_feedback

Transcribe audio or video to text using ElevenLabs Scribe (multilingual, with word-level timestamps and speaker diarization). **Caching:** Results are cached per organization by source URL. Calling `transcribe` with a URL that anyone in your org has already transcribed returns the existing transcript instantly with **no credits charged**. **Inputs (pass exactly one):** - `audio_url` — preferred. In ChatGPT, call `import_chatgpt_media` for an audio file already attached or pasted; call `import_media` only to open the upload picker. Then pass the durable URL. - `video_url` — submitted directly to ElevenLabs when direct Scribe is available; the fal fallback extracts audio server-side. **Google Drive:** Do not pass Google Drive share or download URLs; they are browser flows and are not directly downloadable by Creative Claw. Ask the user to upload the file, then call `import_chatgpt_media` for a file already attached in ChatGPT or `import_media` to open the Creative Claw upload picker. In a local execution environment that already has the file bytes, use `get_upload_url` → PUT → `confirm_upload`. Retry `transcribe` with the permanent Creative Claw URL returned by the upload flow. **Output (returned by check_job once the job completes):** - Inline **basics**: full text, per-speaker formatted text (`formatted_text`), language, duration, speaker count, word count. - Linked **diarization JSON URL** (`diarization_url`) — fetch it for per-word timestamps + speaker IDs. Most use cases only need the inline basics. Returns a job ID — poll `check_job` until status="completed". **Supported formats:** audio — mp3, ogg, wav, m4a, aac. video — mp4, mov, mkv, webm and other formats supported by ElevenLabs. **Pricing:** ~44 credits/hour of audio through direct Scribe v2. A small hold is taken at submit time and reconciled against actual duration on completion. Cache hits cost nothing.

transcribe

Trim a video to a specific time range. Returns a permanent URL to the trimmed video. Each trim costs 2 credits. Specify start_time and either end_time or duration. If only start_time is given, trims 2 seconds from that point.

trim_video

Organize a media asset by setting its name, tags, or description. Assets are entries in your media library (images, videos, audio, 3D models). - **Name**: Unique per user — lets you reference assets by name instead of ID. - **Tags**: Labels for grouping (e.g. "brand", "logo", "draft"). - **Description**: Free-text description. Examples: update_asset({ id: "...", name: "my-logo", tags: ["brand"] }). Clear name: update_asset({ id: "...", clear_name: true }).

update_asset

Update a film project: save the script (logline + shots), advance status, attach generated assets, or change the cast/theme. Shots: pass the full `shots` array to replace the shot list (e.g. when first saving the script), OR `patch_shots` to merge changes into existing shots by id (e.g. after generating one shot's storyboard/clip — set its storyboardUrl/clipUrl/status). Each shot: { id, description, prompt?, narration?, storyboardUrl?, clipUrl?, audioUrl?, durationS?, model?, status? }. Status values: drafting → script_ok → storyboard_ok → rendering → preview_ok → final. Set status to reflect approval gates as the user approves.

update_film_project

Update an existing template's fields. Pass template_id or template_name, then any subset of fields to overwrite. Fields you omit are left alone. Kind cannot be changed after creation. **Replacement semantics:** parameters, model_params, and reference_asset_ids are fully replaced when passed. **Validation:** if html or prompt is replaced, every {{token}} must match a parameter — using the NEW parameters when also passed in the same call.

update_template

Create or update a brand theme. Themes store colors, fonts, logos, a markdown `notes` field (voice / audience / tone / do's-and-don'ts), a reference image, and any brand elements used for consistent media generation. Two modes: - **interactive** (`interactive: true`) — opens the visual editor in the chat for the user to drop fonts/colors/logos and click save. Use this for "edit my theme" / "help me set up a brand" style requests. - **direct** — pass `data`, `images`, and/or `set_default` to mutate without UI. Shallow-merges `data` by default; pass `override: true` to replace it entirely. `images` is always replaced. First image becomes the thumbnail. Creates a new theme if the name doesn't exist. First theme auto-becomes default.
