First of all, THANK YOU for replying Jerry.
This situation had left me baffled, so I will try to be as clear as possible in explaining where I’m at.
I am editing a feature shot on film, and delivered back to me as 23.98 422 ProRes HQ QuickTimes with the mixdown scratch audio synced to them.
The on-set audio recorder recorded the files “at exactly 30fps as required by telecine”.
We then used a program Wave Agent to convert them to 23.98.
I started the project on FCP 6 and then upgraded to a new computer and FCP 7 after a week (as described in the original post). The project itself “upgraded to the newer version” as well.
This method worked for days 1-7, all the files that we synced then are still in sync in the fcp7 project. Yet, when I try to sync any of the other footage past those days, it won’t sync up.
Also, when I tested the footage from days 1-7 by attempting to resync it, it also did not sync.
When I say did not sync, I mean it DRIFTS.
I hope i covered it well enough, sorry it is so long. Hopefully it’s not too scattered.
