2 frame offset in PT

2 frame offset in PT

Hi guys, I could use some help. I'm mixing in ProTools, ver. 8.1 but my problem existed with ver 7 also. I record back into PT using internal bussing, my stems look great, I pop them on to a drive, hand them off to an online editor, and he tells me they have a 2 frame offset. This is a consistent problem. I've talked to everybody I know and everyone's stumped. It doesn't seem to be a delay comp issue. It doesn't seem to be a frame rate issue. All settings have been checked and rechecked. Any help would be great.

Well, if you record into your session, include a 2-pop. If that lines up (session and recorded file), you're good. If it doesn't, you could re-align it and consolidate the file. I usually deliver a file with that 2-pop, so the editor knows where to sync it. That should take care of any offset. There is of course the infamous FCP bug you should read about:

the bug leads to drift not a constant offset.

True, he should read it anyway. Like I said, the 2-pop rules out the constant offset, but who knows what the editor means by: "it's 2 frames out of sync" ;-)

If you are using video card to feed back your TV, check for Video latency.
