Matrox MAX H.264 settings in Apple Compressor
$ Simple GOP Offers a fixed structure in how frames are referenced, and
may be more easily decoded than advanced GOPs.
$ Advanced GOP (short/long) An advanced GOP has more structural
flexibility than a simple GOP, is capable of using more reference frames,
and therefore may provide better overall compression. For a “short”
advanced GOP, the distance between P frames is always 4, and for a
“long” advanced GOP, the distance between P frames is always 8.
¡ Important An H.264 elementary stream file for Blu-ray that was created
using an advanced GOP structure may not be compatible with some Blu-ray
players, and may cause stability issues in Adobe Encore CS4 when burning a
Blu-ray Disc. For compatibility with most Blu-ray players and Adobe
Encore CS4, we recommend using a simple GOP structure when encoding to
Blu-ray.
$ GOP size Select the GOP size in frames (must be a multiple of the
distance between P frames). The GOP size can be either 2048, or an
integer value between 3 and 254.
¦NoteWhen creating an H.264 elementary stream file for Blu-ray, the GOP
size must be less than one second of video. For example, if the frame rate that
you want for your encoded video is 29.97 fps, the GOP size must be 29 frames
or less.
$ Distance between P frames Select the number of frames between P
frames that you want for your GOP structure. This setting can be changed
for a simple GOP structure only.
