Epic Cinematic Transform Video Gen Seedance2.0

Upscale ordinary beats into trailer-scale drama: anamorphic mood in vertical, bold contrast, heroic pacing—WeryAI Seedance 2.0 only. Use when you need hype r...

Security Scan

The skill is internally consistent: it is a Node.js CLI wrapper that calls WeryAI video APIs and only requires the WERYAI_API_KEY and node, which matches its stated purpose.

Purpose & Capability

Name/description (epic cinematic video transform) align with the code and docs: the package contains a Node.js CLI that submits text/image-to-video requests to WeryAI endpoints. Requested bits (node, WERYAI_API_KEY) are exactly what you'd expect.

Instruction Scope

SKILL.md instructions are focused on prompt expansion, validation, and invoking the bundled script (node scripts/video_gen.js). The instructions do not ask the agent to read unrelated system files or additional environment variables; they require image inputs to be public https URLs and mandate showing the expanded prompt before submission.

Install Mechanism

No install spec (instruction-only) and a single JS script shipped alongside documentation. No downloads from arbitrary URLs or package managers are used. This is low-risk for installation.

Credentials

Only WERYAI_API_KEY is required and declared as the primary credential. The script reads only that env var and uses fixed WeryAI endpoints; no unrelated secrets or broad system config paths are requested.

Persistence & Privilege

always:false and no behaviour that persists or modifies other skills/system configuration. The skill makes network calls (required for its function) but does not request elevated system privileges.

Assessment

This skill appears coherent for calling the WeryAI video APIs. Before using it: (1) only set WERYAI_API_KEY if you trust WeryAI and the skill source; do not store the key in the repo; (2) run the script in an isolated or short-lived environment if you want extra assurance; (3) verify the bundled scripts/resources if you want to confirm there are no hidden endpoints (the code uses api.weryai.com and api-growth-agent.weryai.com); (4) ensure Node.js 18+ is available and image inputs are public https URLs; (5) if you do not want the agent to call this autonomously, disable model invocation for the skill in your agent settings.

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 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 (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

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.

Definition of done

Done when the user gets at least one playable Video-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

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:

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:

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.
