Abstract
Apparatus for photographic movie film to video signal conversion comprises a movie film to video conversion apparatus such as a telecine (11) in which the film (1) is aligned frame by frame to derive a video signal, and a video signal processor (16), such as a digital video effects apparatus (12), to process the derived video signal by reference to registration features (2) of the film (1), such as L-shaped registration marks (2) exposed thereon adjacent to each frame (3) of the film (1), to obtain more accurate frame alignment of the video signal.
