When timelines are broken up into chunks that reflect the main elements of your story, you can keep control of your production while making quick, realistic editing decisions based on the elements you have in each of your sequences. By using nesting you can quickly and easily build the final product and still have fast and efficient access to all editing decisions. Nesting is an essential part of editing and incredibly valuable for that final color wash to give mood and substance to your production. In this Premiere Pro tutorial, Andrew Devis demonstrates how to use nesting, and how to think about your projects so that they can be edited in the most efficient way.
