The video file i'm using goes out of sync about half way through it. I've followed a tutorial for virtualdub to fix the audio using the interlacing thingy but afterwards the 1st half goes out of sync. How do i only fix the second half?
Use Virtualdub to create 2 videos out of the movie you have. The first section is with the audio in sync, and he second is the rest, the out-of-sync part. Then use virtualdub just on the 2nd piece to delay/advance the audio as needed.
