NTSC
PAL 2.5, 5, 8, 12.5, 25 (Default)
[Bandwidth Management]
When using MPEG-4 or H.264, it is possible to control the bitrate, which in turn allows the
amount of bandwidth usage to be controlled.
VBR (Variable Bitrate): The quality of the video stream is kept as constant as possible at the cost
of a varying bitrate. The bandwidth is much more efficiently used than a comparable CBR. Set the
image quality to one of the 5 standards: Poor, Fair, Good, Great and Excellent.
CBR (Constant Bitrate): CBR is used to achieve a specific bitrate by varying the quality of the stream. T
bitrates available for selection depend on the image resolution.
[GOP Structure and Length]
Set the maximum number of frames between every key frame. The limit is 1 key frame for
every 120 frames.
