.FCPROJECT File Extension

Video project created by Final Cut Pro X (FCPX), a video editing application; saves a timeline of movie and audio clips, transitions, effects, and other editing information; can be exported and compressed to a variety of final video formats using Compressor, an add-on kit for FCPX.

Final Cut Pro X projects are saved to the ~/Movies/Final Cut Projects/ by default. Project events (video asset files) are saved in a separate directory named ~/Movies/Final Cut Events/.

NOTE: Final Cut Pro projects from previous versions (.FCP files) cannot be imported into Final Cut Pro X projects. However, iMovie projects can be imported (.RCPROJECT files).
