ABSTRACT:
A new 35 mm motion picture film is described which maximizes usage of film stock, and which facilitates acceptance by motion picture theater owners. Acceptance is facilitated by minimizing the cost for projector head conversion and by assuring at least present image quality. The new motion picture format (12, FIG. 4) has film frames (20) of substantially the same size (22, 24) as the mask aperture (H) of the current Wide Screen Academy Format, and uses the same size and spacing of sprocket holes, or film perforations. However, the film frames are spaced apart by a distance (26) that is a noninteger number of perforations, with the spacing being 2.5 perforations in a preferred format (12). A current projector head is converted for showing the new format, by providing new sprocket wheels (14, FIG. 5) with ten teeth, that mount on the same shafts of the projector head as current sprocket wheels that have sixteen teeth.
