If it’s your first import
The first time you open Final Cut Pro, it contains no media and one library containing a single event. You can use the event to quickly import media from your hard disk or directly from a connected camera, and then create a project to start editing.
Import media into an empty event
To import files from a connected camera or from a hard disk: Click the Import Media button and follow the instructions for importing files from a connected file-based camera, from a hard disk, from a tape-based camera, or from a camera archive.
To create a new project: Choose File > New > Project, and follow the instructions for creating new projects.
