Renderingvideo Generator

RenderingVideo preview assistant that uses the public preview flow at POST /api/preview without an API key. Use this when Codex needs to draft or edit RenderingVideo schema JSON, validate it with a temporary 7-day preview link, and return the preview URL and temp identifier.

RenderingVideo Preview Assistant

Use this skill when the task only needs the public temporary preview flow.

Read This First

• Read https://renderingvideo.com/docs/api-and-usage.md before calling the public preview endpoints.
• Read https://renderingvideo.com/docs/json-spec.md before drafting or changing schema JSON.
• Read https://renderingvideo.com/docs/clips.md, https://renderingvideo.com/docs/elements.md, and https://renderingvideo.com/docs/elements/base-clip.md when choosing clip types or fields.
• Read https://renderingvideo.com/docs/animation-and-timing.md when the task changes timing, transitions, or animations.

Enforce These Rules

• Use POST /api/preview for preview creation.
• Send the schema itself as the request body. Do not wrap it in { "config": ... }.
• Do not require or send an API key for this skill.
• Treat the returned preview link as temporary and expiring in 7 days.
• Do not guess fields or routes from memory when api-and-usage.md covers them.

Run The Script

Use the bundled script:

node ./scripts/gen-preview.cjs [path_to_json_file]

Endpoint Mapping

• gen-preview.cjs: POST https://video.renderingvideo.com/api/preview
• Playback URLs: /t/:id or /preview/:id
• Readback endpoint: GET /api/temp/:id

Follow This Workflow

1. Read json-spec.md, clips.md, and the relevant element page.
2. Draft or update the schema JSON.
3. Run scripts/gen-preview.cjs to create a temporary preview.
4. Return the preview URL and temp identifier to the user.
5. If the preview is wrong, revise the schema and generate a new preview.

Keep These API Rules

• The preview body is the full schema JSON.
• Missing top-level meta or tracks should be treated as invalid input.
• The returned preview page is shareable but temporary.
• Prefer viewerUrl when present. Fall back to url if needed.
• Reuse returned tempId, viewerUrl, url, and expiresIn instead of guessing routes.

Return These Fields

• Return tempId, viewerUrl, url, and expiresIn when present.
• Return the full absolute preview URL, not only the relative path.
• If the script or API returns validation failure details, preserve them.

Handle Failures Explicitly

• If the API returns a non-2xx response, surface the HTTP status and response body.
• If JSON parsing fails locally, report that the input file is invalid JSON.
• If the preview expires or becomes invalid later, tell the user to generate a new preview.
