Hi, xvid already has SSE2 code for its most crucial functions. You may want to have a look at xvid.c which lists all the MMX/SSE/SSE2 functions. You could then study those functions that lack a SSE2 counterpart (a candidate for SSE2 might be e.g. sad16bi). If you achieve a speed-up please consider contributing your code and post it here on the list so we can integrate it into xvid.
