Mpeg Layer-3 Avi to AC3 5.1 Avi

[gilbarum]

Hello ppl!

i got an 2 channels avi file, now what i wanna do is to make it an AC3 6 channels avi, how do i do it????
if u can plz give me the entire procedure, tnx!

[anonymez]

you can convert to ac3, but you will still be stuck with 2 channels.

many programs can convert to ac3, such as "besweet" (i also suggest you get the tool "belight" to make it easier to use). software and guides can be found at http://www.doom9.org

i was able to take the sound of the movie using VirtualDub, then convert it to 5.1 sound using GraphEdit, but when i use VirtualDubMod to demux the new sound to the movie its making a 10 GB file!!!!! wtf?

well, its take out the last 2 second out of the file, is it normal?
and how i put this ac3 sound file into the avi file? in VirtualDub i can use only wav files!

[gilbarum]

ok i solve this one using AVIMux, but now i see in VirtualDub that the new avi is AC3 but has only 2 channels, and i want it to be 6 channels, how can i do it?

[tigerman8u]

In reality you can't put info into a audio/video file that isn't there. You can use belight (as stated above) to convert to 5.1 but it won't be a true 5.1 audio.

[anonymez]

like i said, is there any reason you would want to make 6 channels? it is IMPOSSIBLE to make a TRUE 6 audio channel file with a 2-channel source...

[gilbarum]

look at this page:

http://forum.doom9.org/showthread.php?t=83384&highlight=stereo+5.1

there is a guide that show how u make 6 ch audio out of 2 ch, but the thing is its make the new file much larger than the old file, and it may not fit on a 700MB cd

tnx mate

[gilbarum]

not good man, this is only Audio, i need Avi file that give me a 5.1 surround sound

[anonymez]

use virtualdubmod to demux (split) the audio stream from the avi file. encode that audio file to ac3. then mux (join) the audio back to the avi file with virtualdubmod

guide to "virtualdub procedures" here: http://www.doom9.org , incase you are not familiar with it...
