Classic Aperture Mode

In this mode, content appears as it did in QuickTime 7 and earlier. The video track
dimensions are respected. For example, a DV NTSC track appears as 720 x 480.

Clean Aperture Mode

An image’s clean aperture is a region of video free from transition artifacts caused by
the encoding of the signal. This is the region of video that should be displayed.

Classic: no pixel aspect
ratio correction or
aperture cropping

Edge encoding artifacts
