GOP length:
Enter the image interval between I-frames. The value will depend on the GOP
structure selected. It must always be a multiple of the P- and B- frames in the
GOP structure.
The GOP structure "IPB" a length of 4 means that an I-frame is followed by a total
of four other frames, which are alternately P- and B-frames. The resultant image
structure is: IPBPBIPBPBIPBPB …
The GOP structure " IP " can have any GOP length. The " IPB " structure must have
a GOP length that is a multiple of two. The " IPBB " structure has length that are
multiples of three. The GOP structure I requires no GOP length.
