Convert MP3 to AC3 in AVI file

[arendal]

I have problems with burning a DVD converted from AVI.

After a lot of recarch I have found out that the problem is the sound.

The sound is MP3 and when coverting the AVI to DVD using AVI2DVD Beesveet converts the audio to MP2.

My standalone DVD player is not very happy about that.
The software plaers in my PC donæt mind BTW.

I understand that there must be at least 1 AC3 or PCM track on the DVD.

Therefore I need to convert the MP3 sound to AC3 but I have not found any software that has this feature.

I have made a small AVI file with Nandub for testing to save encoding time
;)

Here is my AVI2DVD log:

I understand that there must be at least 1 AC3 or PCM track on the DVD.

Therefore I need to convert the MP3 sound to AC3 but I have not found any software that has this feature.
You can use ffmpegGUI (http://www.free-codecs.com/download/ffmpegGUI.htm).

Ok, thanks!

That gives me a .mp3 file.

How do I use this file now?

I need to get back into the AVI somehow.

You mean .ac3.

I need to get back into the AVI somehow.
Use VirtualDubMod to mux your ac3 file into avi. Set Direct stream copy in Video tab and go to Streams -> Stream list. Disable original track and add your ac3 file. Don't forget to set correct preload/interleave:
80ms/80ms (bitrate 192kbps or 224kbps)


Finally save avi under new file name.
