Abstract
A method is described for converting a strip of film designed for showing at 60 fps (frames per second) to a film that can be shown at 24 fps. Instead of forming the 24 fps film so it alternately contains every second and every third frame of the 60 fps film, each frame of the 24 fps film includes two distinct overlapping successive images of the 60 fps film.
