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. The
Dolby Digital Professional pane opens with the default Audio tab on top. The Dolby Digital
Professional pane contains the following items: basic settings, Audio tab settings, Bitstream
tab settings, and Preprocessing tab settings.
Basic Settings
Use the following basic settings to set up a Dolby Digital Professional (AC-3) job or batch.
• 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.
• Allow Job Segmenting: This checkbox allows you to turn off job segmenting. Since job
segmenting is not used for audio-only encodes, this checkbox is not active with the
Dolby Digital Professional file format. For more information, see Job Segmenting and
Two-Pass or Multi-Pass Encoding.
• Audio, Bitstream, and Preprocessing: These buttons open the Audio, Bitstream, and
Preprocessing tabs described next.
