3D camera

I was wondering if anybody knew of any technique where i can zoom in and zoom out to certain parts of a movie clip? Im not talking about a map or image zoom component. What im trying to do is a website where you see the “big picture” and depending on which section you want to go to, the movie zooms in to part of the “big picture” and content will load.

I was thinking of ,maybe, using papervision3d in order to use its camera to zoom in and out but was wondering if somebody knew of any other alternative. Thanks!
