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.
