Improper VBR audio setting in the source .avi - How to decom

[siridhar]

Hello all

I have a movie (.avi) whose size is 693,886 KB (677 MB). I wanted to write it onto a 80 min - 700 MB CD-R and I experimented with both 'HP-CD Writer Plus' and 'Nero' in vain (tried burning as data CD as well as video CD). Both of them complained that the file size is more than what the CD can hold.

So I decided to split the .avi into two parts. I downloaded 'Virtual Dub', clicked on 'Open video file'. The following message popped up then:

"Virtual Dub has detected an improper VBR audio encoding in the source AVI file and will rewrite the audio header with standard CBR values during processing for better compatibility. This may introduce upto 178742 ms of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder. (bitrate: 157.2 + or - 38.7 kbps)"

When I clicked on "OK" and went on with splitting the file, the resulting two files had their audio out of sync with the video.

How do I solve this problem? What are the tools needed to decompress audio and recompress the .WAV file? A detailed explanation would be appreciated as I am new to the area.

I tried looking for help at http://www.virtualdub.org and on google. But didn't quite get the pointers that would help me solve the case at hand.

Thanks!

To split a movie with vbr audio use Nandub instead of virtualdub, this way you will have no out of sync problems on the new avi. As for converting it, sometimes the audio on your converted mpg will be out off sync. To make sure this doesn't happen, use nandub to save the audio file in wav format. Check the length of the new audio file and see if it's the same as the original movie (check the exact lenght!) if not you'll probebly have to insert some silence at the start or end of the file. Now you can either convert the movie and audio seperatelly and mux them afterwards or you can add the new wav file to the avi, save and burn with nero.
