Good motion starts with a clear brief.

In this workflow a language model writes HTML animation code. A separate browser renderer seeks each frame and FFmpeg encodes an MP4. It is a code-generation workflow, not a video diffusion model.

Vidrial authors the official briefs and illustrative demo scenes. They are original examples, not scraped creator work or claimed model outputs. Community submissions require permission and approval before appearing publicly.

The briefs describe a deterministic HTML contract rather than a model-specific API. Motion Studio offers the models configured for your deployment; a model name on a collection does not mean that model is enabled.

Export depends on the deployed schema, provider and isolated browser worker. The app reports actual availability and plan limits. A queued render becomes downloadable only after output verification.

Reference analysis is intended to extract pacing, palette and timing principles from media you are authorised to use. It does not grant rights to reproduce somebody else's content. Reference analysis stays disabled until its processing path is available.
