Is there a way to create an Mpeg 2 in a custom aspect ratio/frame size or is it confined to predefined setting? I can't seem to get any of my programs to export something other than NTSC or PAL. The size I need is 1320x240. Is there a program that will do it? After Effects, FCP, Compressor and a few oher ones won't do it.
You can certainly make a 1320x240 mpeg. Set your FCP or AE sequence to that size, square pixels and export native. Not sure if Compressor will let you change the size, but there is nothing in the mpeg2 spec that prohibits this size. You may want to try different encoders - Pixeltools and Procoder can set mpeg2 to any size, Cinemacaft can probably too. You just won't be able to make a DVD from your mpeg, but for streaming, etc. you should be fine.
