Change AVI Aspect Ratio

[tahir]

I am trying to change the aspect ratio of a AVI file containg x264 video and AC3 Audio. when i try to open the avi in MPEG4Modifier it give error that OpenDML file not supported. I muxed the file using AviMux and turned off DML but MPEG4Modifier still does not open the file. I forgot what error it gave.
Is there an alternative to MPEG4Modifier.

MPEG4Modifier does not support MPEG-4 V10 (h.264) streams and cant set an aspect ratio.
If you search this forum you should find a tool (maybe it's outdated though) that is able to set the aspect ratio for AVC.
However i higly reccomend using MKV (preferred since your audio is in AC3) or MP4 instead of AVI.

1) demux your avc stream to raw with avi2raw
2) mux your raw avc stream to mp4 with mp4box while setting a par
3) mux the mp4 to mkv with your ac3 with mkvmerge

Thank you bond. But I want the container file to be AVI not mkv.

Thank you bond. But I want the container file to be AVI not mkv.why ?

[tahir]

For simplicity. I give my files to my friend. And some of them complain about the MKV format coz they are not familiar with it. They complain like we cannot open the file. The reason is that they do not install Haali Media Spliter and some of them dont even use Media Player Classic.

Well thats a stupid excuse for not using MKV. Please dont mind.

I second that. xvid + mp3 avi is the most playable thing so far.
As a last resort, you can bundle your encodes with a stable MPC and ffdshow version, hence it won't resolve standalones issues.

This may seem outdated, but can be a solid solution for redistribution and decoding.

Moreover mkv is an issue only for people who hardly succeed in having divx installed, not for those who have x264 and ac3 decoders.

In your case i strongly suggest you to follow bond's advice.
Go for mkv.

Could be a good idea for bundling with encodes too.

for AVC in mp4 i just bundle mplayer and a play.bat which could look like:
mplayer film.mp4 -fs -priority abovenormal

or in your case it could be:
mplayer film.avi -fs -priority abovenormal -aspect x:y

p.s. since mplayer is a bit tricky, iam collecting some usefull combos as of lately:

Thank u guys for ur advise. I will go with the mkv pack idea. smoke i use mplayer for playing mpg1 vcd files. and enable the deblocking and dering with auto levels. its give me great results. i use the command "mplayer *.mpg -vf pp=hb/vb/dr/al"

i would encode to mp4 and tell newbies to use quicktime for playback :D

tough i am not sure if qt is smart enough to handle par ;)
