What software can i use to convert divx+AC3 to divx+mp3

[ivory50]

I want to convert it without extracting the audio as ac3 ,convert to mp3 and attach again

because in that way it can get unsync

I was virtual dubb but it has a fault when i try the conversion :(

I would save it out with full audio processing as a WAV, then add it back in and change the encoding to MP3, then save the whole file, with the video set at 'Direct stream copy'. If you try to do it without extracting, you may have problems.

I also use Lame MP3 in VD for the conversion. Just use the same specs as the AC3 file. I assume you have the AC3 ACM Decompressor in VD already if you were able to open the AC3 audio file. VD and VD Mod use slightly different settings, but they both work the same way. I find VD Mod a little easier to use with audio files than VD.

mencoder with -oac mp3lame and -ovc copy. Could also try AVIDemux.

i tried the avi demux but a pop up screen appear "lame initialization failed"
i installed the mp3 lame but it doesn't help

The Vd software doesn't 'aware' to the fact i installed the lame mp3

Original audio is AC3 48000hz 56000 Bps /448 kbps

You would need to make sure that the audio is downmixed to 2 channels.

ivory50, did you try rebooting after the LAME MP3 install? VD should have found it. With the audio stream, you selected 'Full processing mode', then 'Compression'? Even without LAME, there should be MP3 codec settings there.

But there are lots of other programs that can convert a extracted WAV file to MP3. I don't demux, just save out as WAV, then process to MP3. Then you can add it back in.

Were you able to find the AC3 stream in VD?

Thanks for your Help :roll: :lol: !!!!

I installed the acm , the problem was that it isn't enough to install the lame.exe,
we need also right click on the inf or dll also!! :idea:

For VirtualDub, it's the lame acm codec you need - not the exe.
