You enable it (I don't use it, and V4 is tied up on a long render at the moment, so I can't be specific on the clicks you use to enable . . . I think you'll find it under preferences in the vidcap application) . . . and it will use your time code to detect when you started/stopped your cam during recording, and break those segments into scenes.

This is unlike the approach taken by that other "P" company in thier Studio product. They use contrast variation to detect scenes. Vegas' approach is more predictable, but Studio's approach can also be very useful if your footage doesn't contain a lot of variation in contrast within scenes. Something like a strobe or lighting changes (in a stage play, for instance) might fool the Studio's system into forcing a scene break.

Both systems work, however, if you like using scene detection.

Personally, I find it easier to record in one continuous chunk and then, simply split scenes as I see fit. Often, I want to split the video and re-arrange it without interrupting the sound track (something that's very easy to do in Vegas - last time I tried, I couldn't do it at all in Studio, although things may have changed since I last used that product).

I know you weren't asking for the product comparison, but, I figure understanding how Vegas differs from the other product in this area is part of understanding the nature of how it works.

Good luck . . . hope you find this reply helpful.
