MPEG4 Modifier 1.4.5

Updated: 3 Sep 2012

MPEG4 Modifier allows you to modify MPEG4 videos (XviD, DivX) without re-encoding (change aspect ratio, edit userdata, remove or add packed bitstream, and change interlaced field order).
It can also show information about the video such as the amount of I/P/S/B-VOPs used, whether or not QPel/GMC were used, etc. The video must be in an AVI container.

Important Note:

- Aspect ratio modification works by changing a flag in the VOL headers, which is ignored by most decoders.

Changes in MPEG4 Modifier 1.4.5:

- Ability to export custom quantization matrix to .cqm file.
- Fixed window layout with high DPI settings.
- Supports loading on .NET 4.x runtime (not required; still 2.0 compatible).

Very nice program to get rid of packed bitstreams so the file is playable on your standalone divx player.
