We export same as source quicktimes into Squeeze for nearly all our
encodings. The DVD presets we created crop of two off the top and four
off the bottom. Our other encoding presets generally crop eight off the
top.

interpolation prob in D
I've always been told to crop in even numbers 4 and 2 or 2 and 4 I
guess. Using odd numbers of crop will invert the field order. Not
something I've had to deal with first hand but that's what I've read in
threads over the years. I have experienced the freaky banding when
importing into Avid where the 480 gets stretched to 486.

DVD size. It's better to just crop off 3 lines from the top and 3 lines
from the bottom than to try to divide 486 into 480.
