I know we make a lot of noise here on the video side, and maybe seem petty (HKI topics for example) in a way but I see you asked over on the audio side what Nested timelines were - so I figured I would bring the topic over to the video side as well. Hope you don't mind.
You asked :
I keep hearing about this and have a general idea what users are talking about, but I want to open the discussion up a bit.
So I would say to look at Adobe After Effects. Instead of being a project, or a veg file, we have compositions (Comp 1, Comp 2, etc). So for Vegas you open a new project (Comp 1) and work on it and save it. Now open another project. (Comp 2) Work on that. What AE does that Vegas doesn't is add your comps to the media bin (Project window) so assume for a second that Vegas allows for this as well. Now look into your media bin (project window) and you will not only see your media but also the projects. You want to add Comp 1 to Comp 2? Just drag it over to the timeline (Comp 2) and *poof* - nested element.
For me in an editing scenerio as it relates to Vegas it would help with the sync issue that Vegas has. The file I have been cutting now I open vegas and load the main titles. I also open the main project in anopther instance of Vegas. I cut/re-cut the opening scene and than I render out and drop it into the other timeline. Why do I do it this way? Because it would be a major pain to try and re-edit something at the "start" of a feature film, at least in Vegas. One wrong cut without triple checking settings could mean the rest of the project is now out of whack. So if all you had to do was click on this 'nested timeline' you would not really be affecting the overall timelines material, only the material contained *in* the nested timeline. You edit away on this, add filters, play with audio - whatever - close it back up and your main timeline still is intact.
Think of each 'nested timeline' as one piece of media.
