I am getting a number of audio sync issues while editing out some sketches from a comedy series. The files are all older avi (typical details below). It doesn't happen to all of them, so far maybe 15%. And the sync is less than about 1 second out. It starts off correctly, then seems to be incorrect later. I don't think that the change is gradual, but I may be mistaken. It seems like it is correct up to a certain point, then jumps a bit and is out from then on.
I have seen the problem in two separate source files so far. The other twenty or more other ones appear to edit correctly.
I saw a note in the forum to try setting Control, Obey Sample Times, but if I do this the output avi has no audio at all.
Any suggestions as to what to try?
