Larry R said:What is "Nested Timelines"?
Right now any project in Vegas, no matter how large, is placed on a single timeline. With nested timelines, you have a master timeline and sub timelines (or sequences) that are linked together. So if you have a complicated scene, it can be on it's own timeline and linked to the master timeline. It makes it easy to re-use certain sequences in different projects, by bringing them in as sub timelines. It also makes it *much* easier to collaborate on long form projects.
