A system facilitates the automatic video recording of events which include a moving target. The invention is applicable to all types of videos, but sporting videos are particularly appropriate, where the moving target might be a ball, player, or other target. Broadly, the invention deploys at least two cameras, one (master camera) operating in wide-angle mode to cover a large field of view or the entire scene. At least one second camera operates in a pan/tilt/zoom-in mode relative to the master. A computer analyzes the video input from the first camera and "tracks" the target, preferably using image recognition. The coordinates of the tracked target are transmitted to the second computer to control the second camera(s) to record the event at close-up angles.
