Example MPEG-2 Settings

The following MPEG-2 settings can be used for most general MPEG-2 encoding situations.
Open the MPEG-2 Encoder pane and click the appropriate buttons to access these tabs.

Note: Be aware that many of the settings shown in this example are not suitable for all
video input formats, nor for all encoding situations. Some alternative settings are shown
in parentheses where appropriate. See the sections at the beginning of this chapter for
details on how and when to use other settings.

formats (range varies)

Note: Your choice of bit rate may be influenced by several factors, including the
complexity of your source video, the format and number of your audio streams, and
the total duration of all video clips to fit on your DVD.

Creating MPEG-2 Output Files

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 smartphones 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.
