\*Note: The timestamp seeding seemed to be the magic change on the KBs.

> **🚧 Frame rate and bandwidth**
>
> Remember to set the frame rate to the same value as in your THEOlive channel ingest configuration and make sure that your encoder has a stable connection and enough upload bandwidth. See [Stream configuration](https://optiview.dolby.com/docs/theolive/v1/contribution/stream-configuration.md) for more details.
