What is an FCPPROJECT file?
Project created and used by Final Cut Pro X (FCPX), a professional video editor for OS X; contains information describing a project in FCPX, which includes references to media the user has added from events.
FCPX uses projects to build movies. When you create a project, you bring clips from an event into the project and build a sequence of story elements, which eventually is your movie. Each clip in your project comes from an event.
