GOP Size:
GOP stands for Group of Pictures. It defines the number of frames from one I-frame to the next. Since
an I-frame uses very little compression, while P/B frames use much higher compression, a larger GOP size,
results in smaller file sizes. For more information about I/P/B-frames, see below.
For MPEG-4 there is no maximum GOP size defined. It can be as low as 1 V just an I-frame - or into the
thousands. However, as the GOP size increases, the compression increases, and therefore the more likelihood of
errors. A higher GOP size also results in higher buffering times.
For DVDs the GOP size is 15. The default on the network camera is set to 60, which offers fair compression with
a low likelihood of errors.
z
Peak Bitrate:
This is used to set a maximum bitrate that can be achieved. This is useful for setting bitrates
between the values that are available from the Video Encoder bitrate list.
