Note: If your source video has a frame rate of 24.00 fps rather than 23.98 fps, Compressor
skips one out of every 1000 source frames. If the 24p source video is 23.98 fps, Compressor
transcodes all source frames, without skipping (or repeating) any of them.
MPEG-2 Transcoding Workflow
This section includes step-by-step instructions for setting your MPEG-2 attributes prior
to creating MPEG-2 output files with Compressor. Make your MPEG-2 settings from the
MPEG-2 Encoder pane by either modifying an existing setting or creating a new one in
the Settings tab.
See the following steps for working with the MPEG-2 output file format. For example
values for each of these settings, see Example MPEG-2 Settings.
• Stage 1: Choosing Video Format Settings
• Stage 2: Choosing Quality Settings
• Stage 3: Choosing GOP Settings
• Stage 4: Choosing Extras Settings
Stage 1: Choosing Video Format Settings
It’s important to match the video format, aspect ratio, and field dominance to those of
your source media file. See Video Format Tab for a more detailed description of each of
these settings.
Note: The easiest way to make sure you are matching the source media file is to activate
the Automatic buttons. See About the Automatic Settings for more information.
To open the MPEG-2 Encoder pane and choose Video Format settings
1 Open the Settings tab, then choose MPEG-2 from the Add Preset (+) pop-up menu button.
