VideoRevealed: The Angus Wall Feature in Adobe Premiere Pro
One of the coolest things about Premiere Pro is the many features implemented at the request of feature film editors. In this video, Colin Smith of VideoRevealed talks about a particular feature requested by film editor, Angus Wall (Panic Room, the Social Network). In Premiere Pro, the feature is called "Insert and overwrite sequences as nests or individual clips" and is located in the top right of the Timeline panel, below the timecode. However, many Premiere Pro trainers often refer to this feature as the "nest or not" button. Watch the video to see how it works!
Angus Wall is an Oscar winning director and he helped to shape Premiere Pro into a powerful feature film editing program. This tutorial shows one of the many features that he requested. —VideoRevealed
