Note: This checkbox does not affect the actual pixels in the output file—it only controls
whether information is added to the file that a player can use to hide the edges of the
picture.
If the checkbox is selected: Information is added to the output file that defines how
many pixels to hide to ensure that no undesirable artifacts appear along the edges.
When the output file is played using QuickTime Player, this setting can result in the
pixel aspect ratio being slightly altered.
If the checkbox is not selected: No clean aperture information is added to the output
file. This was the standard behavior in Compressor 3.0.5 and earlier.

QuickTime Video and Audio Settings
The QuickTime Video and Audio Settings buttons appear in the Encoder pane if you
selected QuickTime Movie as the output file format. (The Audio Settings button also
appears if you choose AIFF from the File Format pop-up menu.) You use these buttons
to open the Compression Settings and Sound Settings dialogs, where you can modify
whichever video or audio codec you want to add to the selected setting in the Settings
tab.
By default, both the Video and Audio Settings buttons are enabled, but you can disable
one or the other by deselecting the appropriate checkbox.
Video Codec Settings
The QuickTime Video Settings button provides access to the currently installed QuickTime
video codecs.
For information on how to customize video codec settings, see Stage 2: Adding a
QuickTime Video Codec.
All codecs are compatible with QuickTime, but if you intend to play back the output file
using QuickTime Player, the following delivery codecs are recommended:
H.264
Photo-JPEG
Audio Codec Settings
The QuickTime Audio Settings button provides access to the currently installed QuickTime
audio codecs.
For information on how to customize audio codec settings, see Stage 3: Adding a
