1 m } W ■ ■ S _ sm. if \ Mk ' im, mm SWvW-W?. mm There are two general methods. The Vitaphone uses a disc. In the Movietone method sound is photographed on the film itself. Here you see a camera equipped for both. With the Vitaphone, sounds, picked up by microphones, are recorded on a disc of soft wax. & A m s How Xalkies From “The Photoplay Magazine,” November, 1928 Do you want to know how sound is synchronised with film action? Here is a simple explanation of the best 1929 methods. A large number of inventors are to be thanked for the production of sound pictures. Into their creation has gone the best ideas of the screen, of radio, of the telephone and so on. For the simple presentation of the Vitaphone and Movietone methods shown on these pages, it has been necessary to eliminate many items. Many vital parts of the camera and projector are not shown and certain essentials of a sound film studio are omitted. v-> o \ O ■ r •O: :> ym as it m Hi » o§r l O 1 M, Safe *2? < ; At the left you see a bit of Movietone film. The little margin just at the edge of the pictures is the sound track. Note that the standard size film is used for Movietone. When this film runs through the projection machine, shown directly below, the process is reversed. An ordinary projector is used, plus a sound reproducing unit. Above, a camera with the Movietone equipment simplir fied. The sounds are caught by microphones having the property of changing sound vibrations into electrical vibrations. These vibrations are amplified and, in turn, vary the intensity of the recording light. This recording light is contained in a glass tube inserted at the back of the camera in such a way that the variations in light fall directly upon a narrow strip of the negative film. This occurs at the exact moment the motion picture itself is being recorded. A light-tight barrier, not shown here, is between the narrow strip edge and the rest of the film. are Made 77 ... m'. mm (ti m I E II HUMP • ; m "T" 1 'II The Movietone sound reproducing unit, shown attached to projector at right above, has a light which is focused on the sound strip of film. This sound record passes before the rays, interrupting the constant light according to the photographed vibrations. The variations hit upon a photo-electric cell, are translated back into sound vibrations, amplified and carried to horns behind the screen. The projection room, at left just above, is equipped for both Movietone and Vitaphone. Note the disc upon the Vitaphone turntable, operated by the same motor that runs the projector. Wires carry the sound vibrations from the disc to the loud speakers behind the screen. In either case the voices or sound effects are exactly synchronised with the action on the screen.
