Upload R2 Asset

Use this for large media assets that should be hosted on https://remotion.media/ instead of committed to Git.

Workflow

Find the main worktree:

   git worktree list --porcelain

Prefer the worktree on refs/heads/main, usually /Users/jonathanburger/remotion.

Load R2 credentials from the main worktree:

   --env-file=/Users/jonathanburger/remotion/packages/remotion-media/.env

Do not print secret values. The required variables are AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.

Upload the file to the parser-media bucket using Bun's S3-compatible client:

   bun --env-file=/Users/jonathanburger/remotion/packages/remotion-media/.env -e "import {S3Client} from 'bun'; const filePath='<local-file>'; const key='<remote-file-name>'; const client=new S3Client({accessKeyId:Bun.env.AWS_ACCESS_KEY_ID, secretAccessKey:Bun.env.AWS_SECRET_ACCESS_KEY, endpoint:'https://2fe488b3b0f4deee223aef7464784c46.r2.cloudflarestorage.com', bucket:'parser-media'}); const file=Bun.file(filePath); if (await client.exists(key)) { const stat=await client.stat(key); if (stat.size===file.size) { console.log('exists-same-size', key, file.size); process.exit(0); } } await client.write(key, file); const stat=await client.stat(key); console.log('uploaded', key, stat.size);"

Verify the public URL:

   curl -I --fail https://remotion.media/<remote-file-name>

Replace local asset usage with the hosted URL and delete the local binary.

Do not wrap remote URLs in staticFile(): staticFile() rejects http:// and https:// URLs. Use the URL string directly, for example:

   <Video src="https://remotion.media/example.mp4" />

Run the focused lint or stylecheck for touched packages, then commit and push.
