In SD (720 x 486 NTSC, .9 pixel aspect):
720 / 2.35 = 306 (but this assumes square pixels)
Correct for .9 pixel aspect: 306 * .9 = 275
275 / 2 = 137.5 (so crop 137 or 138 off the top and bottom)
Yah yah, I'm a retard (thats what I get for pounding this out as I'm trying
to leave to go home!) I forgot to subtract the frame height in my SD calc:
REVISED:
In SD (720 x 486 NTSC, .9 pixel aspect):
720 / 2.35 = 306 (but this assumes square pixels)
Correct for .9 pixel aspect: 306 * .9 = 275
---> 486 - 275 = 211
211 / 2 = 105.5 (so crop 105 or 106 off the top and bottom)
