Thanks, Final Cut! That's a really helpful error message!
It's good to know that the project file that was perfectly valid when I saved it on Friday is now corrupted back to the last auto-save. Luckily, I'm basically done with those clips, but my plan to go back and add snazzy lower-thirds is now shot.
Evidence online indicates that it may be a Leopard problem, but it is too early to tell, and may be completely unrelated. So I'm trying to resist the urge to point out that Vista may make me walk through six or seven extra networking dialogs, but it has so far resisted the urge to eat my media projects whole.
That would be hyperbole on both parts, actually. Vista may not have done it, but Pro Tools on either OS X or WinXP certainly had no compunctions about disappearing files when it wanted to, and I still get calls from the team at the Bank sometimes to help them fix problems. As far as I'm concerned, it just points out the real problem with any kind of platform advocacy: computers are not your friend, no matter who made the operating system or how cuddly the icons are. Forgetting this fact probably means a visit from the gaping maw of Final Cut Dog or his destructive, error-laden siblings.
