I've run into a problem with dimension settings in Compressor 3.5 and I haven't been able to figure out where the problem lies. I am trying to compress a 1440 x 1080 self-contained QT file (MPEG-2 created from an HDV sequence in FCP) to an mp4 at 480 x 270. I usually do this by setting the dimension size in Compressor to 25% of source. This time, though, I changed the dimension to 25% of source, and I kept getting a size of 360 x 270. Is there a setting in Compressor that needs to be changed to get the dimension size settings to work correctly?
