[Kelly Griffin] “(1) How do I change the total timeline duration? For example, how do I display a 30-second spot sitting on a 50-second timeline?”
I’m not sure what you mean by “how do I display” but you can make a timeline selection around the 30 second spot and just play that. You can even render just that segment by using the render option [x] Render loop region only. This will limit the render to just the area of the timeline that you have selected.
[Kelly Griffin] “(2) How do I create/switch between several timelines within a project file? For example, within one client project I have to produce two :30 spots and four :15 spots. Can I not just select one timeline or the other within a project, ultimately saving that project that consists of many timelines, or does Vegas think in terms of one timeline being “a project”?”
There is only one timeline per project. If you have events spaced out in different areas, you would have to save just those areas as their own projects, deleting what you don’t need and moving all events to the left.
You can also just render the :30 and :15 second spots on their own as I suggested in the previous answer. In fact, you can make regions around the three spots and use the Batch Render script to just render those regions and all three files will be rendered for you.
What you might not realize is that you can have multiple versions of Vegas open at the same time so you can work on multiple projects at once and cut and paste between them. This might also be a good way of working, although I probably would have put the three spots on the same timeline just as you did and render them as regions.
