Final Cut Pro X: Importing media overview
Importing media into Final Cut Pro is the first step toward making your movie.
With Final Cut Pro, you can:
During import, you assign your media to an event. You can also transcode your media and analyze your media for a variety of issues, such as color balance, the presence of people and shot type, and audio problems.
When you import clips (video, audio, or still images), Final Cut Pro assigns one of five default roles to the video and audio components of each clip: Video, Titles, Dialogue, Music, and Effects. You can also override this automatic role assignment. For more information, see View and reassign roles and Configure audio role assignment during import.
If you want to quickly back up your media (instead of taking the time to import it), you can create an archive.
