Creating MPEG-2 Output Files

Step 1:

Open the MPEG-2 Encoder pane and choose Video Format

It’s important to match the video format, aspect ratio, and field dominance to those of
your source media file. See “

Video Format Tab

” on page 130 for a more detailed

description of each of these settings.

1

Open the Settings tab of the Presets window, then choose MPEG-2 from the Add Preset
(+) pop-up menu button.

The MPEG-2 Encoder pane opens in the Inspector window with the default Video
Format tab displayed.

2

Choose a format from the Video Format pop-up menu:

 NTSC (default)
 PAL
 720p
 1080i (HDV res)
 1080i (Std. res)
 Automatic (SD
 Automatic (HD)

If you are unsure of what your source media file’s video format is, you can choose either
Automatic (SD) for standard definition or Automatic (HD) for high definition and
Compressor will determine the correct setting.

3

Choose an aspect ratio from the Aspect Ratio pop-up menu.

You must determine whether the intended shape of your source video is 4:3 (normal)
or 16:9 (widescreen) before you can choose your aspect ratio.

4

Choose a field dominance setting based on your source media type from the Field
Dominance pop-up menu. For example, for DV choose Bottom First. Or choose
Automatic to let Compressor determine the correct setting.
