Hi all, Appart from the codec used, the compression bit rate depends on the kind of content to be encoded, and other factors such as the resolution of each frame, as well as the structure of the encoded pictures (in MPEG terminology, a GOP). Sports are difficult to compress because they have a lot of movement. On the other hand, news or cartoons ...

Hi all, Let me add to this that the codec used is exactly MPEG-4 part 10, which is known also as H.264. This codec is based in MPEG-2 with some enhances, and halves the bitrate required for a given quality. Regards, dmb01.
