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.
A new commercial theater motion picture distribution film for projecting onto a theater screen, comprising a length of substantially standard 35 mm film stock that has two rows of perforations wherein the perforation spacing distance is uniform and substantially 0.187 inch along each row, and which has new film frames spaced along the length of the film, wherein:
A new commercial theater motion picture distribution film comprising a length of substantially standard 35 mm film stock that has two rows of perforations wherein the perforations are spaced substantially 0.187 inch apart along each row, and which has new film frames each of about 0.46 inch length along the length of the film, wherein:
A motion picture theater distribution film strip comprising:
A method for producing and projecting a commercial motion picture image, by creating a new motion picture release film on substantially standard 35 mm film stock that has perforations spaced substantially 0.187 inch apart along the length of the film, and by projecting new film frames of said new release film on a screen using a projector of common construction that has film-engaging sprocket wheels that are mounted on shafts and that has at least one motor that turns each of said sprocket wheels by a predetermined fraction of a turn every twenty-fourth of a second, where said shafts each could hold current sprocket wheels with a predetermined number of sprocket teeth per 360.degree. to project current film wherein the current film frames each have a length of about 0.46 inch and the current film frames have leading edges spaced four sprocket holes, or substantially 0.748 inch, along the length of the film, comprising:
A method for producing and projecting a commercial theater motion picture image, comprising:
A method for taking and projecting a commercial motion picture image, comprising:
