Configuring the MPEG-4 Video CODEC
You can set the MPEG-4 video CODEC settings of GOP Size, Rate Control Mode, Constant Bit rate,
Average Bit rate, Maximum Bit rate, and Q Initial.
GOP Size
In order to allow high compression rates for digital video it may be encoded into GOPs, or Groups
of Pictures, which consist of key frames (I-Frames) and delta frames (P or B Frames). The Group of
Pictures GOP Size defines the distance between consecutive I-Frames in a video stream.
Rate Control Mode
The Rate Control Mode parameter defines Rate control options for the MPEG-4 encoder. The
options are CBR, VBR, and Constant Q.
In CBR encoding the bit rate is kept constant and is useful for streaming multimedia content on
limited capacity channels.
