Isn't it the job of the scaler to deal with that? I've cropped to 
odd dimensions several times with no problems. It's easy to test 
too: just play the movie with the desired crop (and scale if you 
want). If the color is distorted, something broke. If not, 
there's no reason to think encoding would do any worse.
