Resolution:
The first stream allows for the following output resolutions:
1920x1080, 1280x720, 1024x576, 960x540, 640x480, 640x360 resolutions
The second stream allows for the following output resolutions:
3840x2160@15, 1920x1080, 1280x720, 1024x576, 720x480, 720x408, 640x360,
480x270, 320x240, 320x180 resolutions.
The third stream allows for the following output resolutions:
1024x576, 960x540, 720x480, 720x408, 640x360, 480x270, 320x240, 320x180
resolutions.
Bit Rate:
Users can assign the bit rate of the stream
(Bitrate range is from 32 kbps ~ 102400 kbps noting that bandwidth is shared
by all three streams).
Maximum Frame Rate:
Users can specify the maximum frame rate (fps or frames per second).
Higher frame rates provide smoother video but require higher bit rate
settings..
Output is limited to a maximum of 30 fps.
I Key Frame Interval:
This setting defines how many predicted frames will be used for each actual
frame provided (from 1-1200). Shorter intervals increase video quality at the
cost of requiring higher bit rates in order to look good, it is best to consult the
recommended settings for your ingestion system.
Bit Rate Control Method:
Constant Bit Rate (CBR): The video encoder will encode at a constant rate as
set in bitrate setting.
Variable Bit Rate (VBR): The video encoder will encode at a variable rate, with
a maximum as set in the bit rate setting.
VBR should only be used when working against bandwidth constraints.
Fluctuation Level:
This setting affects how aggressive variable bit rate adjustments will be
(Fluctuate Range is from 1 ~ 6).
Spikes that are too large may affect video quality.
Low levels will not save on as much bandwidth
