Is a good way to compare 2 identical video files sound sync is to drag one in vdub.
look at say a door slam (frame: 40035)
delete all other frames before and after it until im only left with like..2 frames and save it and then load the other version (from say a DVD-R)
go to frame 40035 (where the doors slamming) and save that and if on the second audio its the door slamming but with either no audio or audio but a second later is that a good way of findinbg if sounds out of sync?
But if the sound and video is exactly the same on both files it means both videos have the same sync right?
