Streaming in 1080p is available only for the Medium and higher plan subscribers
Note for FB: Streaming in 1080p is available only to some FB users and pages, and to those who joined Level Up program.
In order to check if you're eligible to stream in 1080p, you need to click on Stream Health in Live Producer. There you'll be able to see your maximum stream resolution.
If you see 720p as your maximum resolution, we don't recommend streaming your video in 1080p via LiveReacting, as Facebook will downgrade it to 720p anyway.
In order to enable 1080p streaming in LiveReacting, just click on a drop-down menu on the top left corner of your project editor, and select the resolution you need.
