MPEG4 Modifier is supposedly one of the best tools for changing the display ratio of any avi (divx/xvid) files, but I've not been able to get it to work at all. Can anyone help? Are there any particular reasons as to why the avi output file may not have a changed ratio when the process is complete? As far as I'm aware I should start MPEG Modifier, click on browse, and select my avi file to add it into the program. I then choose my display ratio by clicking on what one want (or enter a custom value), then I click on 'save as' for the process to begin. Unfortunately the output video is always identical to the original source avi, no matter what. I thought MPEG4 Modifier would do the job, and I'd heard good remarks on how well it was able to work, 'unpacked' or not using the program. I hope someone can help! If anyone would like to try it out (binary): http://www.moitah.net/
You need to use a player that actually respects the PAR. Since all you are doing is altering the header, anything that ignores the header there is going to be no difference. Try VLC or mplayer. For dshow XviD, ffdshow and I believe now DivX decoders support PAR resizing. For XviD make sure it is recent build. I'd go with a 1.2cvs. For ffdshow you need to have allow format changes, etc. enabled in output. For DivX, I guess it needs to be 6.0 or newer?
I think I encoded my video to divx 5. It seems that just about every major media player -WMP, WinDVD et al - ignores the header. Thanks for the info however I'll try both VLC and MPlayer out to see if they make a difference with my newly configured avi's ratio through MPEG4. Even if the above players display the video correctly, I am wondering what the best tool would be for the same result, this time not only altering the header, but the video as a whole? I assume this would this take hrs to process, much like encoding to the divx/xvid format?
Not really upto WMP and other dshow players whether they respect the PAR or not. It is upto the video decoder. Changing the video of course involves resizing and re-encoding.
Unfortunately VLC and Mplayer make no difference, but thanks anyway Can you recommend a simple avi editing tool for cropping and then changing the display ratio, even if it does involve a lengthy process?
Try: http://celticdruid.no-ip.com/test/testar.avi Does it resize? Should be very obvious if it does since it is encoded at 352x576 but set with a DAR of 16:9 which means it should playback at 1024x576.
