PATENT Docket No. 115-11-?48 ABSTRACT OF THE DISCLOSURE An improved method is disclosed for transferring motion pictures from film (4) to videotape (8), with an improved video image quality for moving objects. In the preferred embodiment, the motion picture is filmed at twice the video frame rate, and alternating scanning fields from each pair of film frames (6) are transferred to interleaved fields on a single video frame. The method substantially eliminates image jitter of moving objects, and is particularly adapted to a new 3-D television technique. Various alternate transfer systems are described, as well as a generalization of the invention to account for different film speeds or numbers of fields per frame.
