ok,i have several xvid video clips that seem to have a jitter within the picture, the whole froame does not jitter just some parts, can anyone tell me why this is? i have the most upto date xvid codes on my machine so i dont think that its a code issue(although i could be wrong). will the jitter be removed after i re-encode the movie to mpeg2? any help will be greatfully received. thanx georgyporgy.
