How to convert a VBR divx file to a CBR divx file?

[Brazil]

Hi,

I have a Divx 5.05 vidoe file encoded using a VBR audio mp3 format. I need to convert the audio into a CBR. I guess I need virtualdub to do this but am a little unsure as to what to do next.

I know I have to rip the audio off the original file and then mux it back but am not sure how to do this.

I also have a Divx 5.05 video ac3 file which I would like to convert to a CBR. Would the process be the same?

Could someone please point me in the right direction?

Thanks for you help.

Demux the audio using AVI2WAV
Rename to MP3
Use RazorLame to decode to WAV, and then to encode the WAV to CBR MP3.


It's about the same procedure for AC3.
After extracting with AVI2WAV, rename to AC3, use the AZID program in a DOS window like this:
azid -a filename.ac3 filename.wav (add a -L -3db if you have a 5.1 AC3, and/or a -F wav24 if you have distortions in your WAV)
Then use RazorLame to encode the WAV file to CBR MP3.

Then you can mux the MP3 with your AVI using VirtualDubMod for example.

Thanks for that.
So when I demux does it create two files? One being the audio and one being the video? I think it probably does.

Is the intermediary step necessary, i.e encoding to wav. Cant you just take the audio source from the avi and turn it into an mp3, especially if the audio in one of the files is an ac3 file.

Also can all of this be done within BeSweet GUI instead of using the dos command line?

Are there alternative ways of doing this?

Thanks.

One more thing, I cant find AVI2WAV on the downloads section. Is it part of another program?

just feed BeSweet directly with your AVI file and transcode to whatever you want. (eg, AVI->cbr mp3)

AVI2WAV doesn't make 2 files, it extracts audio only. You don't need 2 files anyway, after transcoding to CBR MP3, you open your original AVI in VDM, disable the old soundtrack, add the new CBR track, and save to a new AVI.
