Live encoder settings, bitrates and resolutions

 

Want to try a faster and easier way to live stream? Go live now using our overhauled Live experience.

Based on your available outbound bandwidth, choose the one quality from below that you can reliably stream.  YouTube will automatically create all of the lower qualities.

Example: If you have 10M dedicated bandwidth for your encoder, you could safely choose to stream 720p quality. 4M for primary encoder, 4M for backup encoder, with room for overhead.

Be sure to test with content similar to your live show.  For example, tests should include audio and movement in the video.  During the event, monitor the stream health and review messages here.
