can you split clips?

I see two possible courses of action: 1) export every bit and piece in QT7; or 2) use keywords and smart collections in FCP X.

I personally would probably go with 2).

Using external media, you could just store your "tape" mov in a designated location, import to libraries as needed (witout any duplication, because media would be left in place). You would then catalog your media inside FCP X; you could start by rejecting those bits and pieces of junk (like where you were stopping the camera or filming the floor...). By selecting "Hide rejected" you would start to see your time divided up in its recordings. Then you could proceed to mark favorites and add keywords - your keyword collections could in essence take the role of the "events".

If it were my project, I would also do as Luis recommends in his 2) workflow.

Also, as a point of info, QT Pro offers many useful tools to users – including the ability to make selects (setting in and out points) and then trimming to the selection (from the Edit menu). If you Save As (the trimmed section) you have two choices – a self contained movie or reference movie. Neither involves requires recompression. Although FCP X doesn't export reference movies (which are very small in size), it will import them and work with them. Meanwhile, your original clip is still available intact.
