I'm using FCP Studio 2. Black Magic Multibridge. I master projects out to DBeta and BetaSP. Lately I've been having trouble keeping sync. I do long programs 60 min plus. They start out ok but lose sync half way through. Yesterday I solved my problem by just playing down from my Seq. Not Mastering or Editing off to tape. But I need frame accuracy. Everything including the Audio is rendered. What do you guys think?
