Triggering renders from Ruby

available from v4.0.232

To trigger a Lambda render using Ruby, install the remotion_lambda gem.
The version should be the same version of the @remotion/lambda NPM package version that you used to deploy your function.

Notes

  • This module is experimental and might have breaking changes in minor versions. Check on this page for up-to-date examples.
  • The implemented methods are renderMediaOnLambda(), renderStillOnLambda() and getRenderProgressOnLambda().
  • We will maintain the Ruby SDK to ensure the fields stay in sync with the Node.js functions.
  • The fields in the input payload are snake_case versions of the Node.js field names.
  • Nested field names, e.g. s3_output_provder.accessKeyId have the original camelCase capitalization.
  • All fields of the response payloads are in camelCase like the original Node.js functions.
  • The maximum input payload size is around 60KB. The workaround for bigger payloads where they get uploaded to S3 is not implemented in the Ruby SDK.
