Abstract: A motion picture film composition method can be provided in which when a first motion picture film on which a first picture is imaged and a second motion picture on which a second picture is imaged are combined, the first motion picture film is converted into a video signal and processed in accordance with predetermined video signal processing to form an intermediate film and a mask film necessary for film composition, and a latent image obtained by superposing the intermediate film and the mask film and another latent image obtained by superposing the second picture film and the mask film are imaged for double exposure to combine the first motion picture film and the second motion picture film with high accuracy so that a combined motion picture film in which the second picture is superposed on the first picture can be made easily.

Abstract: A film image recorded on an initial movie film is converted into a television video signal which is thereafter converted into another film image and recorded an another movie film. The initial movie film includes an identification film part formed in the front end part of the initial movie film and includes first and second identifying patterns which are respectively arranged in alternating frames. By adjusting the timing of the conversion of the television video signal to the other film image in accordance with the image from the identification film part obtained during this conversion, the film image recorded on the other movie film is made to correspond to the film image recorded on the initial movie film.
