Triggering renders from Python

available from v4.0.15

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).

You first need to complete the Lambda setup.

Limitations​

Sending large input props (>200KB) is not supported with Python at the moment.

Rendering a video​

Below is a snippet showing how to initiate a render request and get its status.

Rendering an image​

Below is a snippet showing how to initiate a still image render. Note that it does not require monitoring the render progress.

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.
