I cut six features, a few docs and over fifty episodes of Reality TV in FCP. Most of the stuff you read about organizing is superficial. First, breaking the show in pieces doesn’t help if you version like crazy. The number of sequences affects the size of the project file to much greater degree than the length of the sequences and the number of clips. Second, creating elaborate bin structure is a waste of time. Why put footage into Day 1, Day 2 etc bins when FCP can perfectly sort the list of clips according to the Date Created? The same applies to most of the properties of your footage. Keep all source footage together. Don’t spawn versions. Make sure the amount of tracks in your timeline is reasonable.
