Video images converted from films show unnatural reproduction of movement. To correct this, it is necessary to utilize a motion compensation technique that has already been employed for television standards conversion. We modified an existing high-definition television (HDTV) standards converter by adding the necessary functions for motion-compensated film-to-video conversion. To test the practicality of the modified converter, we detected motion vectors on it by using the video signals of images already converted from film by a telecine. Then we interpolated the images using the detected motion vectors to compensate for movement. The result was less unnatural movement and better quality moving images with respect to film-to-video conversion.
