Yea, this is one of the things I love about Final Cut Pro X by the way. You can make Compound Clips that can be as simple as syncing external audio with video and having them behave as one clip (something DSLR Vegas Pro shooters are always asking for) or have it be an entire secondary storyline with multiple layers. They all sit in the media browser looking just like any other clip. And you do this by simply selecting clips on the timeline and selecting “make compound clip”. I wish it were this easy in Vegas Pro.
It’s important to point out the difference between this and nested projects. With compound clips (or nested sequences), you always have the entire collection of project media available to you to work with while with nested projects, each project has it’s own media pool so it makes it a lot harder to share assets and changes.
BTW, Catalyst Edit supports Nested Timelines. So Sony has realized the shortcomings of nested projects and fixed it in Catalyst Edit. I think over time, Catalyst Edit is going to grow into a capable little NLE. It will take time to re-build the depth of Vegas Pro into it, but starting fresh was a bold move and the fact that it’s available for both the PC and Mac is the right direction to take IMHO.
For now, nested projects is the way to go. Because you can have multiple copies of Vegas Pro open at the same time it makes this a little easier. Also don’t forget to take advantage of the options to right-click a nested project and select “Open in Vegas Pro”. This makes it almost seamless. When I put together some of the tutorial DVD’s that I made for VASST, I use to have a project for each DVD chapter. Then I would assemble the DVD in the order that I wanted later with a master project. It worked out quite well. It sounds like this is what you are trying to do.
