Using Remotion Lambda with R2 - Remotion

R2 by Cloudflare is a popular way to store renders because there are no egress fees.

Create a Cloudflare bucket and set up an API key with Object Read & Write permissions.

Use an s3OutputProvider to store the rendered video in R2:

tsx

import {renderMediaOnLambda, speculateFunctionName} from '@remotion/lambda/client';

// ---cut---
const {bucketName, renderId, cloudWatchMainLogs} = await renderMediaOnLambda({
  serveUrl: 'https://remotion-helloworld.vercel.app',
  // FIXME: Add your function specs here
  functionName: speculateFunctionName({
    diskSizeInMb: 2048,
    memorySizeInMb: 2048,
    timeoutInSeconds: 120,
  }),
  composition: 'HelloWorld',
  region: 'eu-central-1',
  codec: 'h264',
  outName: {
    // FIXME: Use the bucket name from your Cloudflare Storage settings
    bucketName: 'remotion-test-bucket',
    key: 'out.mp4',
    s3OutputProvider: {
      // FIXME: Use the endpoint from your Cloudflare Storage settings
      endpoint: 'https://2fe488b3b0f4deee223aef7464784c46.r2.cloudflarestorage.com',
      // FIXME: Use the Access Key from your Cloudflare settings
      accessKeyId: process.env.R2_ACCESS_KEY_ID ?? '',
      // FIXME: Use the Secret Access Key from your Cloudflare settings
      secretAccessKey: process.env.R2_SECRET_ACCESS_KEY ?? '',
    },
  },
});

Storing the site and assets in R2

Many Remotion users store their bundle and any assets such as input videos in R2, in order to avoid S3 bandwidth costs.
