Selections of Keyframe interval include 1 (default), 2, 5, 10, 30,
60 seconds.
To ensure a clear and smooth streaming, the keyframe interval
value is recommended to be less than or equal to 2 seconds. A
longer interval brings a better picture quality, but requires
more time for the viewers to see the image.

Selections of Bit rate stats duration include 1, 5, 10, 30, 60

A longer Bit rate stats duration is better for motion video. A
shorter period brings stable encoding bit rate which is easy for
network transmission.
