MPEG4 Modifier has found the way to be able to edit any files that are encoded by means of MPEG-4 ASP, like Xvid or DivX, without having to encode them again. Logically, it isn't possible to edit whatever you want, the only options if offers are to change the resolution, the visualization format, the possibility to unpack the Bitstream and change the user data or interlacing. But, furthermore, MPEG4 Modifier allows you to easily see much more detailed information.
The great advantage of this software is that, since it doesn't require any time to recode anything, it can be used in emergency situations. If we can't play or view a file properly somewhere, it can always be quickly modified with MPEG4 Modifier.
