Remotion CLI

Run commands as npx remotion ... or via package scripts if the project defines them. The CLI requires Node.js 18+ and for render operations a Chrome/Chromium installation (or use npx remotion install-executables).

Development loop

1. Scaffold: npx create-video@latest or clone a template. For non-interactive: npx create-video@latest --blank ./my-project.
2. Author: write compositions using /remotion-core.
3. Fast feedback while editing: npm run dev opens Remotion Studio on localhost:3000.
4. Check in Studio: scrub the timeline, verify all frames render, check all compositions with npx remotion compositions src/index.ts.
5. Render a draft: use --concurrency=1 first to detect non-determinism bugs.
6. Preview with the user: open Studio, hand the URL, ask whether to revise or render final.
7. Render only after approval: use high quality codec for delivery.
8. Verify the output: confirm the file exists, is non-empty, and has the expected duration via ffprobe.
