Cropping rules

[mach]

What are the rules on cropping before encoding an xvid movie? I discovered that when cropping a movie in vdub then trying to encode it with xvid would crash vdub if aspect ratio wasn't divisible by 2. Now I have encoded the movie but it crashes all the players. Could this be a cropping problem?

when cropping the video you have to take care that the resulting resolution is mod 16 (or even better 32) - in other words the height and width have to be divisible by those numbers!

it might work with lower numbers, but you will get optimal results when using those mods!
