Audio properties
•
Channel layout: Use the pop-up menu to set the audio channel layout. For more information,
see About audio channels on page 67.
•
Sample rate: Use this pop-up menu to set the number of times per second that music
waveforms (samples) are captured digitally. The higher the sample rate, the higher the audio
quality and the larger the le size.
•
Sample size: Use the pop-up menu to manually set the sample size of the audio signal.
•
Copy audio tracks from source: Select the checkbox to copy the audio les from the source le
(instead of re-encoding them during the transcoding process).
•
QuickTime settings: You can add an audio codec that you’ve installed on your system to
customize the Compressor setting. To change the codec used in your setting, or to modify
the codec’s properties, click the Change button and use the controls in the Sound Settings
window to modify the codec as appropriate. After you click OK and close the window, the
setting’s audio properties update to show your changes.
Audio eects
For a list of available audio eects and instructions on how to add an audio eect to a setting,
see Add and remove eects on page 76.
Work with destinations
View and modify a destination’s properties
Destinations consist of one or more settings combined with an automated job action that
is performed after transcoding. For example, if you apply the built-in Publish to Facebook
destination to a source le, Compressor uses the setting to create a QuickTime movie le
optimized for viewing on the web and then runs a job action that publishes the le to your
Facebook account.
When you select a destination in the Settings pane, its properties are shown in the
Destination inspector:
•
Name: Displays the name of the destination.
•
Description: Displays a description of the destination.
•
When done: Use this pop-up menu to modify the job action associated with the destination.
For a list of each job action’s properties, see Job action properties on page 59.
