Final Cut Pro X: roles
Roles are metadata text and color labels that you assign to clips in the browser or the timeline. They provide a flexible and powerful way to manage your editing workflow. You can use roles in Final Cut Pro to organize clips in your events and projects by function or category, control the arrangement of clips in the timeline, create and manage captions, and export separate video or audio files (also known as media stems) for distribution, broadcast, audio mixing, or post-production. Roles have distinct colors that let you instantly recognize clips with a particular role in the browser and the timeline.
