## Description

The composition job did not start because the combined size of the media sources passed to the composition is too large to process.

### Possible Causes

Due to fixed hardware constraints, Twilio is not able to compose all the media tracks specified in the composition create request. Check the maximum size on [Known limitations](/docs/video/api/compositions-resource#known-issues)

### Possible Solutions

Please reduce the scope of the composition by excluding some of the sources to verity that they are below our maximum size. If not possible, please [contact us](/help/contact) and provide a description of the media files you are attempting to compose.
