Mark,
I have some suggestions for you, but you,ve got to be willing to “think different”. Ready?
First, get rid of the idea that ALL of your media needs to be in a single project… It doesn’t !
Second, use the finder level for organizing your media.
Third, go buy CATdv. If you don’t know about it, there’s a forum for it right here on the cow. Check it out. You can have CATdv and FCP open at the same time. Switch back and forth between the two . Search in CATdv, edit in FCP. Try it. I think you,ll like it.
If this isn’t a workable idea, consider multiple projects based on media type: interviews, b-roll, scenes, etc. You can have them all open simultaneously.
Hope this helps.
Mark
