In my first test, I worked off a 1280×720 square pixel timeline, and exported to Compressor. I outputted using a DVCPROHD 720p60 preset that I edited to be 1280×720 square pixels (instead of 960×720 anamorphic pixels). But the resulting .MOV file seems to still be 960×720 anamorphic pixels.
Is the codec itself forcing the horizontal downsampling? Is 960×720 the only resolution the codec is able to produce?
Is there another delivery codec someone can recommend that can do 1280×720 square pixels?
