If the source resolution is 1920 x 1080, please set the video bitrate (bps) as
1280*720 from the drop-down menu due to that the upper limit for the resolution is
1280*720.
Because the upper limit for the recommended video bitrate for the Facebook
platform is 4000kbps, so, it is a must for users to set the video bitrate to less than
4mbps.
During the streaming, the Key Frame must be sent for every two seconds which is the
same as Youtube platform’s demand.
The setting values for the 2 seconds I Frame Interval are shown as following table.
