Hey, I have tried hard subbing a avi file, but after I add the subs to the movie, the audio isn't in sync. When I use virtualDub to open my AVI file it gives me a message "VirtualDub 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 up to 17420ms 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: 164.5 23.2 kbps)" Any help would be appreciated. Thanks.

Are you using 'VirtualDubMod' ?? - VirtualDub does not offer to rewrite audio.

If it's VirtualDubMod, elect to keep the VBR header.
Click 'Streams' 'Stream List' and 'Save WAV'
Disable the existing stream by double clicking on it then 'Add' the WAV file.
Right click on the new stream and 'Full Processing' 'Compression' and select Lame mp3 4800, 128, cbr, stereo, if available.
That way you replaced the VBR with CBR audio.


Lame MP3 codec
Right click on 'LameACM.inf' file and Install
