what size should the video be?

Is this audio sync only an issue when capturing with HDLink? Does the same problem occur when capturing using Aspect HD from within Premiere Pro (i.e., batch capture in PP with scene detect unchecked)? I guess my question is, when capturing from within PP, is it best to always check 'scene detect'?

It is best to use scene detection, yes. You can turn scene detection off when re-batch capturing without issue (assuming your batches don't cross a lot of scene boundaries.)

Thanks, David. I just turned on scene detection in PP for an HD capture (using batch) but don't see any evidence that it worked. I tried this with a tape that has several obvious camera stops/starts. Should i see different AVI files? (I don't -- it's just one long file.) There's no evidence of different scenes within PP either.

I guess batch superceeds scene detection.

Strange. I have scene detection selected within batch. Are you saying that it's possible that batch + scene detection = batch + no scene detection (in reality)?

I'm not seeing any audio sync issues with this tape, even at the end, but given what I've heard about audio sync problems for other people I'm hesitant to make this my standard workflow.

So I guess the bottom line is: no batch capture in PP with AspectHD because the scene detect doesn't work?

What are you using batch for?
I just read my entire tape(s) with scene detect on.
Or, I start it at an in point/out point if I do not want the entire tape, but have multiple scenes

Dave, I have always used batch in the past so that the capture would be repeatable (after deleting the main captured file, for example). It's a pretty useful tool.

I just tried record + scene detect and it worked fine (detected scenes). I could not get 'in/out' capture + scene detect to work however. It just hung while in 'seek' mode. (My in/out points were set correctly.)

I had to recapture a tape the other night and the scene capture seemed to been frame repeatable.

I used in/out with scene detect 2 nights ago and it worked great for me.
Dont you love all these differences. :o)
