So you’re inheriting a project? And it sounds like they have media scattered all over the damn place and they can’t find it all? ….the classic FCP blunder.
1) do you need a complete clone of the project?
2) how much media do you really have? we’ve had 2 feature films this year that fit snugly on a 1TB firewire
My 1st instinct is MM will make more of a mess than not. I’ve never used it on a long form project, like you, just things under 10 minutes. If there are any speed ramps or lots of imported graphics… seems like a disaster would probably ensue. But I may be wrong, especially with FCP 6. I’m just jaded.
