I Key Frame Interval:
Affects the quality of the video compression. This setting defines how many predicted frames will be used
for each actual frame (from 2-150). Shorter intervals increase video quality at the cost of requiring higher
bit rates in order to look good.
Bit Rate Control method:
CBR (constant bit rate): video encoder will encode at a constant rate as set in bitrate setting
VBR (variable bit rate): video encoder will encode at a variable rate with maximum as set in bit rate setting,
allowing for low motion scenes to use less bandwidth.
Fluctuate level
This setting affects how aggressive variable bit rate adjustments will be (1-6). Spikes that are too large may
affect video quality. Low levels will not save on as much bandwidth.
Second Stream (See parameters for first stream).
