Customizing Lambda output destination

By default a render artifact is saved into the same S3 bucket as where the site is located under the key renders/${renderId}/out.{extension} (for example: renders/hy0k2siao8/out.mp4)

You can modify the output destination by passing a different filename, writing it into a different bucket or even upload it to a different S3-compatible provider.

Customizing the output name​

To customize the output filename, pass outName: "my-filename.mp4" to renderMediaOnLambda() or renderStillOnLambda().

On the CLI, use the --out-name flag.

The output name must match /^([0-9a-zA-Z-!_.*'()/]+)$/g.

Customizing the output bucket​

To render into a different bucket, specify the outName option to renderMediaOnLambda() or renderStillOnLambda() and pass an object with the key and bucketName values:

tsx
const { bucketName, renderId } = await renderMediaOnLambda({
  region: "us-east-1",
  functionName: "remotion-render-bds9aab",
  composition: "MyVideo",
  serveUrl:
    "https://remotionlambda-qg35eyp1s1.s3.eu-central-1.amazonaws.com/sites/bf2jrbfkw",
  inputProps: {},
  codec: "h264",
  imageFormat: "jpeg",
  maxRetries: 1,
  privacy: "public",
  outName: {
    key: "my-output",
    bucketName: "output-bucket",
  },
});
tsx
const { bucketName, renderId } = await renderMediaOnLambda({
  region: "us-east-1",
  functionName: "remotion-render-bds9aab",
  composition: "MyVideo",
  serveUrl:
    "https://remotionlambda-qg35eyp1s1.s3.eu-central-1.amazonaws.com/sites/bf2jrbfkw",
  inputProps: {},
  codec: "h264",
  imageFormat: "jpeg",
  maxRetries: 1,
  privacy: "public",
  outName: {
    key: "my-output",
    bucketName: "output-bucket",
  },
});

If you like to use this feature:

  • You must extend the default Remotion policy to allow read and write access to that bucket.
  • The bucket must be in the same region.
  • When calling APIs such as downloadMedia() or getRenderProgress(), you must pass the bucketName where the site resides in, not the bucket where the video gets saved.
  • The key must match /^([0-9a-zA-Z-!_.*'()/]+)$/g
  • The bucketName must match /^(?=^.{3,63}$)(?!^(\d+\.)+\d+$)(^(([a-z0-9]|[a-z0-9][a-z0-9-]*[a-z0-9])\.)*([a-z0-9]|[a-z0-9][a-z0-9-]*[a-z0-9])$)/.

This feature is not supported from the CLI.

Saving to another cloud​

Available from v3.2.23

You can upload the file to another S3-compatible provider.

  • List of supported providers (non-exhaustive): Cloudflare, DigitalOcean Spaces
  • List of unsupported providers (non-exhaustive): Azure Blob Storage (not S3 compatible)

You must pass an outName as specified above and also provide an s3OutputProvider like in the example below.

tsx
const { bucketName, renderId } = await renderMediaOnLambda({
  region: "us-east-1",
  functionName: "remotion-render-bds9aab",
  composition: "MyVideo",
  serveUrl:
    "https://remotionlambda-qg35eyp1s1.s3.eu-central-1.amazonaws.com/sites/bf2jrbfkw",
  inputProps: {},
  codec: "h264",
  imageFormat: "jpeg",
  maxRetries: 1,
  privacy: "no-acl",
  outName: {
    key: "my-output",
    bucketName: "output-bucket",
    s3OutputProvider: {
      endpoint: "https://fra1.digitaloceanspaces.com",
      accessKeyId: "<DIGITAL_OCEAN_ACCESS_KEY_ID>",
      secretAccessKey: "<DIGITAL_OCEAN_SECRET_ACCESS_KEY>",
    },
  },
});
tsx
const { bucketName, renderId } = await renderMediaOnLambda({
  region: "us-east-1",
  functionName: "remotion-render-bds9aab",
  composition: "MyVideo",
  serveUrl:
    "https://remotionlambda-qg35eyp1s1.s3.eu-central-1.amazonaws.com/sites/bf2jrbfkw",
  inputProps: {},
  codec: "h264",
  imageFormat: "jpeg",
  maxRetries: 1,
  privacy: "no-acl",
  outName: {
    key: "my-output",
    bucketName: "output-bucket",
    s3OutputProvider: {
      endpoint: "https://fra1.digitaloceanspaces.com",
      accessKeyId: "<DIGITAL_OCEAN_ACCESS_KEY_ID>",
      secretAccessKey: "<DIGITAL_OCEAN_SECRET_ACCESS_KEY>",
    },
  },
});

In this example, the output file will be uploaded to DigitalOcean Spaces. The cloud provider will give you the endpoint and credentials.
