For some reason Apple doesn't make this easy. It should be intuitive, but I couldn't figure it out. All I wanted to do was to import movies from iPhoto into Final Cut Pro X.
I had to Google it to see what the solution was, an all I found were peopel complaining that they couldn't figure it out.
It's easy, but not intuitive.
Here's how to Import iPhoto Movie Files into Final Cut Pro X (FCP X):
STEP 1: Choose the menu item FILE > IMPORT > FILES
STEP 2: CLICK 'Import Files'
STEP 3: In the left hand part of the FCP X 'Import Files' dialog box, CLICK Movies, then select the movie files that you want to import.
Note: These are iPhoto Movie Files. I know, it's not intuitive.
