Package a ZIP

What validators check before your package is accepted.

Recommended layout

my-template/
  package.json
  remotion.config.ts
  src/
    Root.tsx
    Composition.tsx
  public/
    preview.mp4      # recommended for autoplay
  README.md

Required

Valid .zip archive
package.json with a Remotion dependency (remotion or @remotion/*)
Remotion entry such as src/Root.tsx or src/index.tsx
No node_modules/ in the ZIP
Under size limit (default 200MB)

Safety limits

Compressed ZIP under platform max (default ~200MB)
Uncompressed total and per-file caps (zip-bomb protection)
Entry count capped (thousands of files rejected)
Paths with .. / absolute escapes should be avoided (buyers extract locally via CLI)

Buyer-facing polish

Stable slug — CLI users pin it forever
README: Node version, npx remotion studio, composition ids, main props
Dark-friendly preview (catalog is dark UI)
Tech/SaaS demos sell better than generic loops on Remotemp

If validation fails

The UI and Upload API return a clear error list. Fix the package and re-upload. A bad ZIP never overwrites a previously good version.

Note: we validate structure, not every runtime bug. Broken runtime code may still pass static checks — always test locally with Remotion Studio before submit.
