MPEG4 Modifier 1.4.5

Updated: 3 Sep 2012 | Freeware | 84KB | Downloads: 113941

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).

This little gem saved me from the nightmare of non-square pixels.

If your video looks stretched vertically when you play it - even when you know it shouldn't - simply open it up in MPEG4 Modifier (it doesn't have to be a MPEG file - it works for AVIs too) and select 'Square Pixels' under aspect ratio.
