Cinephonic Eight cameras, the picture/sound separation was 52 frames. Fifty six frames was the same physical distance as magnetic sound was specified for the 16mm film format (or 28 frames in that format). Optical sound was never specified as the format had insufficient space for an optical track. Packaged movies Although standard 8 mm was originally intended as a format for creating amateur films, condensed versions of popular cinema releases were available on the format up until the 1970s, for projection at home. These were generally edited to fit onto a 200 ft reel. Many Charlie Chaplin films, and other silent movies were available. Short, silent versions of sound films with dialogue titles added were also released, including W. C. Fields' The Bank Dick, which emphasized the chase sequence at the end of the movie. Also available were newsreels covering the previous year and short versions of sound cartoons. Castle Films was the major supplier of these films. The Walt Disney Studio released excerpts from many of their animated feature films, as well as some shorts, in both Standard and Super 8, some even with magnetic sound. New releases of material were not stopped until the late 1970s in the US.
