Conform Aperture
. Check to enable, then choose one of these options:
- Disabled
- Classic
- Displays the image without applying either the pixel aspect ratio or the clean
aperture. The image is displayed using the track header dimensions, meaning the
decompressed picture is scaled into the track header dimensions if the encoded
dimensions are different.
- Clean Aperture
- Both the clean aperture and the pixel aspect ratio are applied. The
dimensions of the track become equal to the clean dimensions which are equal to the
display dimensions (with conformed contents).
- Production Aperture
- Applies the pixel aspect ratio but not the clean aperture. The
image is presented in the correct aspect ratio, but the extra pixels outside of the image
that exist in the source material will be presented. The track dimensions are equal to
the result of applying the pixel aspect ratio.
- Encoded Pixels
- The encoded pixels are displayed intact in this mode. Under this mode
the track dimensions are equal to the encoded dimensions. No scaling or
transformation takes place.
Note:
The Clean Aperture selection should not be used in conjunction with the
Enable CLAP Atom selection. Only one or the other should be used.
Enable CLAP atom
. Enables the QuickTime Clean Aperture atom.
