Choose your video and audio settings (see the tasks below for additional instructions):
•
Enabled/Disabled/Pass-through: Use these pop-up menus to enable or disable Video and Audio
settings. Enabled means the video or audio track will be included in the output movie. Disabled
means the video or audio track will be excluded from the output movie. Pass-through (audio
only) means Compressor will copy the audio into the output movie without modifying it. An
example of this might involve high-definition (HD) files with multitrack audio that you want to
convert to standard-definition (SD) files without disturbing the audio tracks.
Note: If you export a sequence from Final Cut Pro to Compressor (by choosing File > Export >
Using Compressor) and apply a setting with “Pass-through” selected, the audio portion of the
setting is changed to a PCM setting with the sequence’s setting and channel count, but with
only a single track created on output. If you require audio pass-through for a Final Cut Pro
project, export a QuickTime movie (by choosing File > Export > QuickTime Movie) and import
the movie into Compressor.
Important:
If a setting has “Pass-through” selected, the Filter pane audio filters are not
available. Additionally, the Frame Controls pane retiming controls will not correct the audio,
potentially causing synchronization errors with the video.
