Is there any safe way to upgrade to Tiger while working on an FCP Project and make sure all is ok? The reason why I ask is that I'm still on Jaguar and want some of the updates that Tiger can give me. Here's the scenario: 20 minute DV project - unfinished 1. All Media and render files are NOT on the main boot HDD (2nd scratch disk HDD) 2. FCP project and program files are on main boot HDD I will be doing a few more special FX before the edit is done. Then I will be having the music and sfx professionally done - on a different computer. This means that I'll have to keep the project in tact on my computer while this is being done so that when it's complete, I can marry the sound and full scale video. After that, will have to professionally color correct the footage (probably tape to tape) - I don't want to color correct on FCP myself. Once that's done I could obliterate the system, load on Tiger and just "capture the whole movie" to the scratch disk as a new project in FCP and make DVD's from that. But I really want to upgrade sooner (now! / April 15) to get some other things that Tiger offers that Jaguar does not. I don't want to screw up hours and hours and hours of work. Your suggestions would be greatly appreciated.
