I have one AVI file where the sound became unsincronized after some minutes. How can I fix it ?
Thanks |

Assuming the first part is in sync and the remainder is out of sync (by a constant amount).
Load the file.
Scrub to the end of the synced part and select it with the flags.
'Video' > 'Smart Rendering'
'Video' > 'Compression' and select the same codec as the source (XviD?).
'File' > 'Save as AVI..' - name it p1
Delete the selected part (Del key).
'Audio' > 'Interleaving' > 'Audio skew correction', insert 500 or -500 and play the clip.
Refine the skew value until the clip is synced.
'File' > 'Save as AVI..' - name it p2
Exit and restart VirtualDub.
'File' > 'Open video file' and select p1.avi
'File' > Append AVI segment' and load p2.avi.
'Video' > 'Direct stream copy'
'File' > 'Save as AVI..'
You may be able to use 'Direct stream copy' instead of 'Smart Rendering' for the video, if you can select on key frames.
