Cutting/audio out-of-synch

[rjc7394]

I am cutting an avi (with vbr audio) in VDUBMod. Result is audio's out of synch. I tried reencoding to mp3 to correct the vbr problem but end up with vbr audio. How can I correct the vbr and synch problem?

Hi!

Converting .AVIs with VBR-MP3 Audio

Simply use NanDub or VirtualDubMOD (Different than standard VirtualDub), to save the audio stream as an Uncompressed PCM (WAV) file as follows:
1) Load your original .AVI into NanDub

2)Set "Video" to "Direct Stream Copy"

3) Set "Audio" to "Full Processing Mode" (NanDub only -For VirtualDubMOD>"Streams>"Stream list">>rightclick on the listed audiostream and then select "Full Processing Mode")
From the "Audio" dropdown menu, select "Compression" and choose "No compression(PCM)" (NanDub only - For VirtualDubMOD>"Streams>"Stream list">>rightclick on the listed audiostream and then select "Compression" and choose "No compression(PCM)")

4) From the "File" dropdown menu, select "Save WAV" (In VirtualDubMOD, "Save WAV" is located under the "Streams" drodpown menu) (Enter a new filename with a ".WAV" extender).Click on "OK"

5) Then save the .AVI as a silent .AVI (NanDub - set "Audio" to "No audio" after you've saved the WAV file. - For VirtualDubMOD>"Streams>"Stream list">>click on the listed audiostream and then select "Disable").


Then close NanDub and restart it
Set "Audio" to "No audio" (Not necessary under VirtualDubMOD)
Load your silent .AVI
Set "Video" to "Direct Stream Copy"
Under "Audio" click on "WAV Audio" and load your .WAV (In VirtualDubMOD, Streams>>Add)
Set "Audio" to "Full Processing Mode" (In VirtualDubMOD, Streams>>Rightclick on the listed audiostream, click on "Direct Stream Copy")
From the "Audio" (In VirtualDubMOD, "Streams") dropdown menu, select "Compression" (In VirtualDubMOD, rightclick on the listed audiostream, click on "Compression") and choose the appropriate .MP3 settings. Click on "OK"
From the "File" dropdown menu, select "Save as AVI" (In VirtualDubMOD, "Save as") and save your file with a new filename.

I fixed it by reencoding audio in BeSweet first. For some reason I ended up with vbr when using VDUBMod.

Congratulations on resolving your dilemma!
And thanks for posting how you accomplished it ;>}

I suppose you can also improve an out of sync by this tool without audio reencoding :
