Immersion/Intergration

I have a a nice realistic .avi clip of fire. If I would want, for instance to show a log burning in that fire how would I do it?

Would the answer to this question generically apply in any case in which I wanted to integrate an object or the subject of one clip into the context of another?

Thanks,

Bill

Ina a word, compositing.
To do it well is not easy. Take your burning log. It's pretty easy using a number of techniques that you can do in Vegas to add it into a scene. Except when a log burns it creates light and that light illuminates the objects in the scene that you're compositing it into. Even harder to simulate, it's not a constant light.

The simplest to use tool in Vegas for compositing is probably the bezier curves. You can use them to cutout part of one video and then composite that into the video on a track below. There's some pretty decent examples in the manual.
