Exporting Audio

If you export your video from Remotion, the audio is automatically included.
Additionally, this page shows you can export the audio only, or omit the audio, and how the export process works.

Audio Only​

Exporting as mp3, aac and wav is supported:

Command Line​

To render only the audio via CLI, specify an extension when exporting via CLI:

sh
npx remotion render src/index.ts my-comp out/audio.mp3

or use the --codec flag to automatically choose a good output file name:

sh
npx remotion render src/index.ts my-comp --codec=mp3

renderMedia()​

To render only the audio via the server-side rendering APIs, use renderMedia() and set the codec to an audio codec.

render.js
tsx
await renderMedia({
  composition,
  serveUrl: bundleLocation,
  codec: 'mp3',
  outputLocation,
  inputProps,
});

renderMediaOnLambda()​

To render only the audio via Lambda, use renderMediaOnLambda() and set the codec to an audio codec and imageFormat to none.

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: 'mp3',
  imageFormat: 'none',
});

Lambda CLI​

To render via the Lambda CLI, use the npx remotion lambda render command and pass the --codec flag:

sh
npx remotion lambda render --codec=mp3 https://remotionlambda-qg35eyp1s1.s3.eu-central-1.amazonaws.com/sites/bf2jrbfkw my-comp

Excluding audio​

Command Line​

Pass --muted to not export audio.

sh
npx remotion render --muted

renderMedia()​

Pass muted: true to renderMedia() to mute a render.

render.js
tsx
await renderMedia({
  composition,
  serveUrl: bundleLocation,
  codec: 'h264',
  muted: true,
  outputLocation,
  inputProps,
});

renderMediaOnLambda()​

Pass muted: true to renderMediaOnLambda() to mute the render.

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',
  muted: true,
});

Lambda CLI​

Pass --muted to npx remotion lambda render to mute a render when using the Lambda Command Line.

sh
npx remotion lambda render --muted https://remotionlambda-qg35eyp1s1.s3.eu-central-1.amazonaws.com/sites/bf2jrbfkw my-comp
