AOTC was filmed digitally but released on both DLP and 35mm projectors. Some people here suggested that the CGI was rendered at a higher resolution than 2002 DLPs could display (which is 1280x1024 with a 1.9:1 anamorphic lens). Note that the filmed elements were filmed at 1980x1080 with a 1:1 pixel aspect ratio and 3:1:1 subsampling (horizontal luma subsampling of 1440 pixels and horizontal chroma of 480 pixels). Essentially that's 1440x1080, and that was then cropped to 1440x800. But the release resolution for DLPs was 1280x1080.
