D1/DV PAL 1.09 1.07 D1/DV PAL Widescreen 1.46 1.42 This discrepancy is limited to these older, standard-definition formats for which clean aperture differs from production aperture. This discrepancy doesn't exist in newer formats. New projects and compositions created in After Effects CS4 and later use the correct pixel aspect ratio values by default. Projects and compositions created in After Effects CS3 or earlier are upgraded to use the correct pixel aspect ratios when these projects are opened in After Effects CS4 and later. Note: If you have a custom interpretation rules file, then you should update it with the correct pixel aspect ratio values. If you use square-pixel footage items that are designed to fill the frame in a composition with non-square pixels, you may find that the change in pixel aspect ratios causes a difference in behavior.

This setting can also be appropriate for footage that was transferred from film or for customized projects. Footage has a 720x486 or 720x480 frame size, and the desired result is a 4:3 frame aspect ratio. This setting can also be appropriate for footage that was exported from an application that works with nonsquare pixels, such as a 3D animation application.

This discrepancy is limited to these older, standard-definition formats for which clean aperture differs from production aperture. This discrepancy

doesn’t exist in newer formats.

New projects and compositions created in After Effects CS4 and later use the correct pixel aspect ratio values by default.

Projects and compositions created in After Effects CS3 or earlier are upgraded to use the correct pixel aspect ratios when these projects are

opened in After Effects CS4 and later.

Note:

If you have a custom interpretation rules file, then you should update it with the correct pixel aspect ratio values.

If you use square-pixel footage items that are designed to fill the frame in a composition with non-square pixels, you may find that the change in

pixel aspect ratios causes a difference in behavior. For example, if you previously created 768x576 square-pixel footage items to use in a PAL

D1/DV composition, you should now create those items with square-pixel dimensions of 788x576.

Composition settings presets for square-pixel equivalents of standard definition formats have changed as follows:
