MPEG4 Modifier for Windows

MPEG4 Modifier is a tool that allows you to modify AVI attributes without the need for re-encoding. It specifically works with MPEG4 ASP video files, which are part of the XviD and DivX codecs. With this program, you can easily adjust the aspect ratio, both for presentation and pixels. Additionally, you have the ability to modify user data and alter the interlaced field order.

MPEG4 Modifier offers a range of other useful functions as well. You can delete or add 'packed bitstream', view data about the quantity of B-VOPs used, and determine if the video includes GMC or QPel. This tool aims to provide flexibility and customization options for your MPEG4 videos, all without the need for re-encoding.
