About the Dolby Digital Professional Encoder Pane
This section contains detailed information about the various tabs within the Dolby
Digital Professional (AC-3) Encoder pane of the Inspector window.
You make your Dolby Digital Professional settings using the tabs described below, by
either modifying an existing setting or creating a new setting in the Settings tab of the
Presets window. The Dolby Digital Professional pane opens with the default Audio tab
on top and contains the following items:
 File Extension: This field displays the Dolby Digital Professional file extension (ac3)
automatically after the Dolby Digital Professional output format is selected from the
File Format pop-up menu or the ( + ) pop-up menu in the Settings tab of the
Presets window.
 Allow Job segmenting: This checkbox allows you to turn off job segmenting. It is
relevant only if you are using Compressor with distributed processing and with two
pass or multi pass encoding. (The Compressor 2 distributed processing feature is
limited to computers that have either Final Cut Studio or DVD Studio Pro 4 installed.)
For more information, see “
Encoder Pane ” on page 43.
 Audio, Bitstream, and Preprocessing: These buttons open the Audio, Bitstream, and
Preprocessing tabs described next.
