What are roles in Final Cut Pro primarily used for?

Roles in Final Cut Pro serve as a powerful organizational tool that allows editors to categorize audio and video clips in their projects efficiently. By assigning roles, you can streamline the editing process, making it easier to manage and export your project for mixing or post-production.

When you assign specific roles to different audio tracks—such as dialogue, sound effects, or music—this organization not only helps during the editing phase but also simplifies the final export process, especially when working in collaborative environments or when sending files to audio mixers or other team members. Additionally, roles can help you isolate and adjust tracks quickly, enhancing your workflow when dealing with complex audio setups.

The other options listed involve specific editing tasks or effects that do not relate directly to the conceptual organization of clips, which is the primary function of roles. Therefore, focusing on organizing audio and video clips for easier export and mixing is the correct understanding of the purpose of roles in Final Cut Pro.
