A system and method for registering the frames of film with respect to an aperture (32) in a motion picture projector. A registration reference mark is applied to each frame corresponding to the location of the frame on the film. When the film is intermittently stopped in the projector's film gate (22), the registration reference mark is read to determine the location of that frame relative to the immediately preceding frame. If the frame in the gate (22) is misregistered, the gate is moved to correctly register the frame prior to projection. By properly registering the frames, the 'jitter' and 'weave' associated with conventional projectors is eliminated and resolution of the projected film image is enhanced.
