Chapter 9 Creating MPEG-1 Output Files 121
MPEG-1 Transcoding Workflow
This section gives step-by-step instructions for setting your MPEG-1 attributes prior to
creating MPEG-1 output files with Compressor. Make your MPEG-1 settings from the
MPEG-1 Encoder pane by either modifying an existing setting or creating a new
setting. See the following steps for working with the MPEG-1 output file format.
Example MPEG-1 Settings
The settings you use depend on whether you are encoding for use on the web or in a
DVD project.
Encoding for the Web

rates when encoding stereo audio
