Matchmove software is used to place computer graphic (CG) elements into live action scenes that have a moving camera. It tracks the camera movement in 3D space and that 3D geometric data can then be used in a 3D animation program to place elements or characters so that they match the cameras movement, hence the name matchmove. What I'm doing is taking that tracked geometric data and having the 3D application (Maya) calculate, using the Y axis data, the degrees from 0 (zero) that the camera has panned and then rendering that output in a compositing application (Shake). In the case of the zoom shots I'll use the Z axis data to calculate the focal length and the tracking shots will use the X axis data to calculate the distance the camera has moved.
The clip is short and not of such great quality but I wanted to keep it large in order to better see the tracking markers.
