Organize clips by roles
You can organize clips by roles, which are metadata text labels assigned to clips.
When you import clips (video, audio, or still images), Final Cut Pro automatically assigns one of five default roles to the video and audio components of each clip: Video, Titles, Dialogue, Music, and Effects. You can also create custom roles and subroles and assign them to clips.
You can view and reassign roles in the Browser, the Timeline Index, or the Info inspector. For example, you could easily identify all your dialogue clips and play them back in isolation from other audio clips. See View and reassign roles.
