In non-linear editing, which task is not typically performed directly on the timeline?

• A. Trimming clips
• B. Adding transitions
• C. Layering video and audio tracks
• D. Exporting the final master

Answer: (D)

On the nonlinear editing timeline you actively shape the sequence by trimming clips, inserting transitions, and stacking multiple video and audio tracks to build the final mix. These actions happen directly in the timeline workspace as you edit the order, duration, and relationships of clips. Exporting the final master, however, is a separate step that occurs after the edits are finished. It involves rendering and encoding the project to a deliverable file using the software’s export or render function, taking the assembled timeline content and producing a standalone video. So the task not performed on the timeline is exporting the final master.
