Coding with Xvid is most efficient when the picture is cropped to a multiple of 16 horizontally and vertically.
Worst case is to leave black borders which fall somewhere in between a 16x16 macroblock, because the sharp transition between the useful picture and the black border consumes extra bits for encoding.
