FrameVideo CLI

Everything runs through npx framevideo. Requires Node.js >= 22 and FFmpeg.

Workflow

1. Scaffold — npx framevideo init my-video
2. Write — author HTML composition (see the framevideo skill)
3. Lint — npx framevideo lint
4. Visual inspect — npx framevideo inspect
5. Preview — npx framevideo preview
6. Render — npx framevideo render

Lint and inspect before preview. lint catches missing data-composition-id, overlapping tracks, and unregistered timelines. inspect opens the rendered composition in headless Chrome, seeks through the timeline, and reports text spilling out of bubbles/containers or off the canvas.
