Not only that. The Memory Head is only for rotation, pitch yaw etc. But you still need the linear tracking information (dolly shots) and angular information of every joint in the case of a crane shot. The solution so far seems to be a full motion control system such as Kuper Control. The problem is not so much camera movement but camera location, and it is trickier than it sounds. If you are not using a motion control setup the establishing the location of the optical center of the lens (whis is what you need) on a frame per frame basis is almost impossible with current positioning systems, The magnetic ones get thrown off by the metal body of the camera gear, optical systems are quite imprecise etc. We are working on a complex system which involves gravimetric accelerators and precison gyroscopes to triangulate the position of the nodal poin. So far quite frustrating but getting closer. This is to use in case the camera is placed in a non-motion controlled gear. Arturo
