Apple Compressor 3 - Manual (Page 221)

Compressor provides the tools you need to create exceptional MPEG-4 transcoded files.
MPEG-4 Part 2 (known as MPEG-4 video in QuickTime 6) plays an important role in the
evolution of standards for the Internet and wireless multimedia industries, where it has
been widely adopted.
Use MPEG-4 Part 2 anywhere you want to be compatible with MPEG-4 Part 2 devices or
players, such as the millions of 3G mobile phones and digital still cameras that capture
and play back MPEG-4 Part 2 video.
H.264, also known as MPEG-4 Part 10, is a newer technology than MPEG-4 Part 2, providing
up to four times the frame size of video encoded with the MPEG-4 Part 2 codec at a given
data rate. But, just as MPEG-1 and MPEG-2 are still used in the industry today, MPEG-4
Part 2 will continue to be used.
Note: MPEG-4 Part 2 is both a QuickTime codec (MPEG-4 Video) and an output format.
This chapter discusses MPEG-4 Part 2 as an output format.
