A system and method for tracking objects between multiple frames of a video is described. One method for tracking objects begins with a viewer initially identifying an object in a frame of video. If the viewer requires zooming, he can also select a scale factor for the identified object. Once the user has identified an object for tracking, the computer system identifies a reference point on the object and identifies the motion vectors for that reference point. Using the motion vectors, the computer system can track the identified object as it moves across the screen and can reposition an image acquisition area to track the location of the identified object in subsequent video frames.
