Converting Xvid audio from AC3 to MP3

[Janusian]

I have recently bought a Creative Zen Vision M, which is rather splendid. One frustration I am having is that I have some Xvid files which have an AC3 soundtrack, which the player does not support, so I need to convert the audio stream.

I tried START as recommended elsewhere on this site, but that led to the audio being out of sync, and the resulting files kept crashing WMP, so I wasn't about to risk them on my player.

Is there any other tool, which will recode preferably just the audio, or the whole file to a supported format.

(supported video formats are DivX, XviD, MPEG-1, MPEG-2, MPEG4-SP, WMV9, Motion-JPEG - supported audio formats are MP3, WMA, WAV)

Any advice gratefully received.

If you have AC3 ACM Decoder and LAME MP3 installed you can use Virtualdubmod to do this.

Open the avi and click on Streams-StreamList. Right-click on the audio track and select Full Processing. Right-click again and select Compression. Select LAME MP3, and set a bitrate and sample rate. Click OK. Click on Save WAV, and save your new audio track. Click on Add, and load the track you just created. Click on the AC3 audio track and click on Disable. Finally, right-click on the MP3 audio track and select Direct Stream Copy. Click OK.

Click on File->Save As to save a new version of the avi file, with MP3 audio.

I saw that thread in my search, but as the words

The source AVI files are not changed in any way,

appeared in the first line, and I need to change the source file I did not read on. Maybe I should have done.

OK, I am doing something daft. I did exactly as you said, and I ended up with a 44GB Video file. Please could you give me some clue as to my obvious error! The original file was only 348MB

Use DirectStream Copy

Use DirectStream Copy

If you don't then the video will be saved as uncompressed.

That seems to have done the trick just dandy.

Thank you all for your help. I shall now sit on the train tomorrow and enjoy my new toy!
