MPEG4 Modifier |
Modifies a MPEG-4 ASP video (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.

When an DivX/XviD is found, MPEG4Watcher checks if the file contains a packed bitstream, if it does, it gets unpacked to another directory.

I tried so many programs like abcavi to correct the aspect ratio of a downloaded avi file but without any success. Then I stumbled upon Mp4modifier and it did in 2 seconds flat what I have been trying for so many days. Just great.

i used it to change the aspect ratio of an XVID AVI - just clicked on the aspect ratio i wanted it to be, & name of file to save it as, little progress bar took less than a minute. worked great. im presuming the unpacking of the bitstream would be just as easy. great stuff, does exactly what I wanted it to. Thanks.

I want to thank the authors of this MPEG4Modifier for solving my problem. I had an AVI in an incorrect aspect ratio. I used VLC and modified the playback until I found an acceptable aspect ratio, the download and ran this tool and it quickly created a version of the file that works perfectly. Thank you.

Tried using this program with the hope I could change the FPS without having to reencode. Unfortunately, the options are pretty limited and basic, so I wasn't able to use it to achieve the FPS I wanted. It would be a great help if the program offered more flexibility, such as an option to switch to other frame rates like 23.976. Still, the program is useful and it works.

I use this tool primarily for the purpose of making TV Eps compliant with my Zensonic DVD/MPEG4 player. While MPEG4 Modifier is absolutely indispensable, in my view it has a couple of shortcomings, and could do with a simple cosmetic (and ergonomic) enhancement. Shortcomings: 1: To determine if audio is not correctly aligned with video frames, I have to use Gspot. If the Audio needs re-alignment I have to use AVIMux_GUI to correct it. Would it be possible to have MPEG4 Modifier add this funcionality as a feature? 2: MPRG4 Modifier shows if an AVI has GMC or Qpel. If it does, I have to re-encode the episode so it becomes Standalone MPEG4 player compliant. Are there any plans to add the ability to fix the GMC and Qpel problem within MPEG4 Modifier? Enhancement: It's just a little thing, but considering the amount of screen real estate available these days, why have the "Video Info" as a separate popup? There's not that much info there that it couldn't be all on the first screen. It would be much more convenient! The author has no way to contact him to make suggestions. I hope he reads these comments. Thanks for a really useful utility.

Excellent program for unpacking avi files. As mentioned previously, version 1.2.0 seemed to have a couple of issues, leaving 1.1.0 being the choice for most. However, the latest version seems to be stable, and very slick with its new progress bar.

been using this (version 1.2.0) to unpack bitstreams on xvids for use on my yamada 6600 player, which cause jumpy playback, does this very well indeed and is a simple process check the bix and change the "p" to a "n" in the user data box by clicking edit and resaving the file 5minute job, only problem is with this version its gives me a no dummy n-vop error message aobut 50% of the time, so i have to go back to using version 1.1.0 whic is why i rate it 5 for functionality but over all between the 2 versions ive been able to get the job done 100% of the time
