Audio Sync Problem
Well I have seen a ton of posts about this problem, but none seem to answer my question.
I shot three tapes, and I have captured all of them the same way. Finally when I get to the end, and I add the third mpeg the audio is off-sync.
If I play the file in Media player the audio is fine all the way though. I am using premiere CS4, does anyone have a helpful suggestion?
UPDATE: So I tried it all over again, the video clip starts out fine, but as it progress teh audio slows down. However, I looked and it says its 48000 and teh project is too. I am so confused.

Adam,
If I understand you correctly, you were editing with mpeg. You should not edit with mpeg, it will create problems as you are learning. It is highly compressed, meaning it won’t provide information the editing software needs to create the proper syncing.
Instead convert your mpeg to a format that is lossless. That means that every frame is a keyframe. A keyframe has all the information that the frame should have.
I’ve forgotten exactly, but mpeg I think has only something like 1 of 11 frames that has(ve) the full information.
I hope this helps.

What would be a good lossless format to edit in? I am pretty new at this.

It will depend on what you have available to you. You can download all sorts of different tools to do this type of thing, but if you have Adobe Media Encoder you can use that to convert to Microsoft AVI or quicktime. Basically just select none for your codec in the video tab (with QT you might also try PNG or animation for smaller file sizes). What you want is a result that is all keyframes. Your files will be very large.
I am hoping that you didn’t actually shoot in an mpeg format…which it seems you may have. If so, you can still convert, but you will have already lost quite a bit. But it should…should…solve the sync problem.
I’d suggest reading up on all of this kind of stuff. It actually is quite interesting if you’re into it, and it will help immensely in understanding your tools.
