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. The Dolby Digital
Professional pane opens with the Audio tab on top.

Basic settings
Use the following basic settings to set up a Dolby Digital Professional (AC-3) job or batch:

Extension: This field displays the Dolby Digital Professional file extension (.ac3) automatically
after the Dolby Digital Professional output format is chosen from the File Format pop-up
menu or the Create a New Setting (+) pop-up menu in the Settings tab.

Allow Job Segmenting: This checkbox allows you to turn off job segmenting. Because job
segmenting isn’t used for audio-only encodes, this checkbox is dimmed when you choose the
Dolby Digital Professional file format. For more information, see

Job segmenting and two-pass

or multi-pass encoding

on page 249.

Audio, Bitstream, and Preprocessing: These buttons open the Audio, Bitstream, and
Preprocessing tabs described next.

Audio tab
All the most important Dolby Digital Professional settings are accessible in the Audio tab.
