Encoder Settings Reference

When you create a quality live event stream, your viewers are more engaged with the content you share. Use the information in the following tables to configure your encoder settings. These settings enable you to provide a quality live stream for your viewers.

🚧
Be sure to test your encoding settings before your live event begins.
