Use when you need hype reels, faux movie poster motion, or image-to-video with blockbuster lighting. SEO: epic cinematic video; trailer style short video." tags: [cinematic, epic, trailer, drama, short-video, video-gen] metadata: { "openclaw": { "emoji": "🎬", "primaryEnv": "WERYAI_API_KEY", "paid": true, "network_required": true, "requires": { "env": ["WERYAI_API_KEY"], "bins": ["node"], "node": ">=18" } } } user-invocable: true --- # Epic cinematic trailer style transform (Seedance 2.0) **Blockbuster read in 9:16:** dramatic skies, volumetric god-rays, slow push-ins, percussive motion cuts implied in prompt, huge scale cues. **Dependencies:** `WERYAI_API_KEY` + Node.js 18+. This skill uses **only** `SEEDANCE_2_0`. When you run the CLI, **`{baseDir}/scripts/video_gen.js`** must exist; **[`WERYAI_VIDEO_API.md`](resources/WERYAI_VIDEO_API.md)** must exist under **`{baseDir}/resources/`** (supply both via publish or pre-use assembly). Full commands and JSON fields: see **`resources/WERYAI_VIDEO_API.md`**. **No other Cursor skills required.** ## Prerequisites - `WERYAI_API_KEY` **must be set** before running `video_gen.js`. - Node.js **18+**; image inputs **must** be public `https` URLs (no local paths). - **Model (caller / agent):** The bundled `video_gen.js` **requires** a non-empty `model` in JSON—if `model` is missing or blank, the CLI exits with **`MISSING_PARAM`** (no default model). The script **does not** enforce this skill's allowed model in code: you **must** set `"model":"SEEDANCE_2_0"` for this package and show it in the confirmation table before submit—see [`WERYAI_VIDEO_API.md`](resources/WERYAI_VIDEO_API.md) (`model` row). - Each `wait` run may consume credits; re-run creates new paid tasks. ## Security, secrets, and API hosts - **`WERYAI_API_KEY`**: Treat as a secret. Only configure it if you trust this skill's source; it is listed in OpenClaw metadata as **`requires.env`** / **`primaryEnv`** so installers know it is mandatory at runtime (never commit it inside the skill package). - **API hosts (fixed in `video_gen.js`)**: Video tasks use **`https://api.weryai.com`**; the models list uses **`https://api-growth-agent.weryai.com`**. Child skills must not document or rely on URL environment-variable overrides—only **`WERYAI_API_KEY`** is read from the environment. - **Higher assurance**: Run generation in a short-lived or isolated environment (separate account or container), and review `scripts/video_gen.js` (HTTPS submit + poll loop) before production use. ## Prompt expansion (mandatory) `video_gen.js` does **not** expand prompts. Before every `wait --json`, turn the user's short or vague brief into a **full English production `prompt`** that **re-styles** the described event into this skill's look. **When:** User input is short, vague, or missing cinematic detail. **Exception:** They supply a finished long prompt within **2000** characters and ask you **not** to rewrite—still show the **full** text in the confirmation table. **Always add:** shot size and angle; camera move; lighting and color grade aligned to this skill; subject action paced to `duration`; **one clear payoff**; platform framing (**9:16** unless user chose another allowed ratio); if `generate_audio` is **true**, describe ambience / SFX in generic words (no copyrighted music references). **Length:** Stay within **`prompt_length_limit` 2000** for `SEEDANCE_2_0`; trim adjectives before losing the core transformation beat. **Confirmation:** The pre-submit table **must** include the **full expanded `prompt`**. ### Style transformation checklist - **Lens grammar:** wide establishing → medium hero; subtle dolly in. - **Light:** chiaroscuro, rim for silhouette reads, storm or golden hour motivation. - **Trailer rhythm:** build–pause–hit within `duration` seconds. - **Scale:** crowds implied, vast plates, foreground debris parallax. - **Action:** destiny-weighted gestures, cape or coat motion—even on mundane tasks played epic. - **Sound (if on):** braams, drums, whooshes—generic descriptors only. **Fits:** Big moments, sports hype, product hero shots, mythic storytelling. **`### Example prompts`** below are **richness targets only**—always derive from the user's actual brief. ## Workflow 1. Confirm the request matches this skill (text-to-video and/or single image-to-video). 2. Collect the user's **brief**, optional **`image`** URL, and tier (**best** / **good** / **fast**)—all map to **`SEEDANCE_2_0`** with different duration defaults (see **Recommended models**). 3. **Expand prompt (mandatory):** Unless the user opted out with a finished long prompt, expand using `## Prompt expansion (mandatory)`. **Do not** submit only the user's minimal words. 4. Validate **`model`** is **`SEEDANCE_2_0` only**; validate `duration`, `aspect_ratio`, `resolution`, `generate_audio` against the frozen tables. 5. Show the confirmation table with the **full expanded `prompt`**; wait for **confirm** or edits. 6. Run `node {baseDir}/scripts/video_gen.js wait --json '...'`. 7. Parse stdout JSON; return `videos` URLs or explain errors. 8. When presenting playable URLs to the user, use **Markdown inline links only** (e.g. `[Video](https://...)`). **Do not** wrap user-facing links in code fences. ## CLI reference ~~~sh node {baseDir}/scripts/video_gen.js wait --json '{"model":"SEEDANCE_2_0","prompt":"…","duration":10,"aspect_ratio":"9:16","resolution":"720p","generate_audio":true}' ~~~ **Full reference:** **[`WERYAI_VIDEO_API.md`](resources/WERYAI_VIDEO_API.md)**. ## Definition of done Done when the user gets at least one playable **[Video](url)**-style link, or a clear failure with next steps. Submitted `prompt` must be the **expanded** prompt unless the user explicitly opted out. **Never** use another `model_key` in this skill. ## Boundaries (out of scope) - Do not use **any model other than `SEEDANCE_2_0`** for this package. - Do not link to `weryai-model-capabilities.md` or shared `../references/` paths; use **`resources/WERYAI_VIDEO_API.md`** for CLI/API details. - Do not use local file paths for `image`; never embed the secret value of `WERYAI_API_KEY` in files. - Do not invent API fields; do not send `negative_prompt` (not supported for this model). - Do not wrap user-facing playable URLs in Markdown code fences. ### Example prompts - `Pouring water → treated like mythic libation, storm light, massive scale mist` - `Opening a laptop → beam of light, dust particles, heroic low angle, 9:16` - `HTTPS athlete still → slow epic zoom, stadium haze implied, dramatic rim` --- ## Model and API constraints (frozen for this skill) > Derived from `node {baseDir}/scripts/video_gen.js models` alignment at authoring time; re-run `models` after platform upgrades. **This skill is locked to `SEEDANCE_2_0` only.** ### Text-to-video | model_key | durations | aspect_ratios | resolutions | Audio | negative_prompt | prompt limit | |-----------|-----------|---------------|-------------|-------|-----------------|---------------| | `SEEDANCE_2_0` | 5, 10, 15 | 9:16, 1:1, 16:9 | 480p, 720p | Yes | No (do not send) | 2000 | ### Image-to-video (single `image`) | model_key | durations | aspect_ratios | resolutions | Audio | negative_prompt | upload_image_limit | |-----------|-----------|---------------|-------------|-------|-----------------|-------------------| | `SEEDANCE_2_0` | 5, 10, 15 | 9:16, 1:1, 16:9 | 480p, 720p | Yes | No (do not send) | 3 | --- ## Recommended models | Tier | model_key | Notes | |------|-----------|-------| | ⭐ Best (default) | `SEEDANCE_2_0` | Prefer **`duration` 10 or 15**, **`resolution` 720p**, **`generate_audio` true** for fullest mood | | 👍 Good | `SEEDANCE_2_0` | Balanced: **`duration` 10**, **`resolution` 720p**, audio per user | | ⚡ Fast | `SEEDANCE_2_0` | Snappy: **`duration` 5**, **`resolution` 480p** or **720p**, audio optional | Tier only changes **duration / resolution / audio** defaults—**never** the model. --- ## Default parameters | Field | Value | |-------|--------| | Model | `SEEDANCE_2_0` (fixed) | | Aspect ratio | `9:16` | | Duration | `10` (use `5` for punchy; `15` for slower ceremony) | | Resolution | `720p` (`480p` allowed) | | Audio | `true` unless user wants silent | --- ## Scenario: Text-to-video style transform **Flow** 1. Capture the user's mundane event in one or two sentences. 2. Expand into English with the **Style transformation checklist**; keep identity generic unless user names a character. 3. Confirmation table → user **confirm**. 4. Execute: ~~~sh node {baseDir}/scripts/video_gen.js wait --json '{"model":"SEEDANCE_2_0","prompt":"<expanded>","duration":10,"aspect_ratio":"9:16","resolution":"720p","generate_audio":true}' ~~~ 5. Return `[Video](url)` links. --- ## Scenario: Image-to-video style transform **Before use:** `image` must be `https://` and reachable. 1. Plan how the still **re-styles** in motion (props, light, environment) without breaking likeness if the user requests preservation. 2. Expand prompt; add `image` to the confirmation table. 3. After **confirm**: ~~~sh node {baseDir}/scripts/video_gen.js wait --json '{"model":"SEEDANCE_2_0","prompt":"<expanded>","image":"https://…","duration":10,"aspect_ratio":"9:16","resolution":"720p","generate_audio":true}' ~~~ 4. Return `[Video](url)` links. --- ## Loop seam (optional) If the user asks for a **seamless loop**, append a short English trio at the **end** of the expanded prompt: `seamless loop`, `perfect loop`, `ends where it begins`—no separate API flag. > Generated for skill `epic-cinematic-transform-video-gen-seedance2.0`.
