Triggering renders from Python

available from v4.0.15

EXPERIMENTAL

This feature is new. Please report any issues you encounter.

To trigger a Lambda render using Python, install the remotion-lambda package using pip, by executing pip install remotion-lambda from your python project. Use the same version as the remotion version you are using from NPM, e.g. pip install remotion-lambda==4.0.15 (see newest version).

Breaking changes

4.0.82

  • The data field is now input_props.
  • RenderParams has been renamed to RenderMediaParams.
  • RenderProgress has been renamed to RenderMediaProgress.
  • RenderResponse is now RenderMediaResponse, and its fields have been updated: renderId is now render_id, and bucketName has been changed to bucket_name.
  • The following types have been added: CostsInfo, Privacy, ValidStillImageFormats, LogLevel, OpenGlRenderer, ChromiumOptions, CustomCredentialsWithoutSensitiveData, CustomCredentials, OutNameInputObject, PlayInBrowser, Download, DeleteAfter. These can be used for the fields on RenderMediaParams and RenderStillParams.

Note the following before continuing:

  • You first need to complete the Lambda setup.
  • Sending large input props (>200KB) is not supported with Python at the moment.
