That's basically it Opera, but Syntheyes actually simplifies it even further. You shoot your video, and then import it into Syntheyes. Often, all that you have to do is ask it to "autotrack". I'm working on a shot now that took my P4 2.4 about 20 minutes to analyze. It reports back with a report of possible "targets" which it has assigned to various points on your video. These are indicated by yellow "X" marks on your clip. You choose one of them to be an origin, and then a couple of others so it can calculate relative distances between them. (You choose a tracker by clicking on it and fill in approximate X,Y,and Z co-ordinates relative to your origin.) Once you have input this information, you rerun the track, and it then computes what movements you made with your video camera, which is exported into a Lightwave, Cinema, Houdini, Truespace, Particle illusion.......Poser scene. In this case, Poser's main animating camera would track as you had shot your live video. Now when you load your character into Poser with your video in the background when the camera moves, it is including all of the proper perspecive in relationship to your character. With the new Shadow catcher, you should be able to render directly right from inside Poser. Now Vicky can be rendered in a real world temple, complete with fluid, live action footage. It has been used for alot of big screen productions, including most recently "The Aviator". I just received an email saying that the new script is for P6 export. Great... now I need P6.
