I've posted this on the FCP forum but will also try here.
I am running the latest version of FCP and have the latest Decklink HD Extreme card fitted.
My problem is when I export anything to a self contained movie file out of Final Cut Pro it is 5 frames out of sync.
If I move the audio back 5 frames and re-export then it is fine.
It is also the same when I export to any format via compressor
I have looked at all the possible settings I can find and no joy.
Any help on this would be appreciated
I have been having this same issue. I don't understand what happened, but I didn't change anything and yet everything I export is off, and it varies with each export. I think that there is something going bad with my Decklink Extreme HD card....
