Movie Makers (Jan-Dec 1950)

14 NOW, SOUND ON FILM! New CineVoice 16mm. sound camera puts professional pictures within amateur reach EVER since the first 16mm. sound on film projector was introduced, the home movie maker has dreamed of the day when a precision 16mm. camera would be available at reasonable price for making talking pictures at home. The new Auricon Cine-Voice sound on film camera is the answer to that dream. Designed and built in Hollywood by the Auricon Division of Berndt-Bach, Inc., this new 16mm. sound camera features simplified controls, weighs only 12% pounds and is priced well within reach of the advanced 16mm. movie maker. It can be used for making talking pictures indoors or out, during vacation trips, at birthday parties, or even during baby's bath, all with theatrical brilliance and clarity. The Cine-Voice camera is driven by a constant speed electric motor, providing on a 100 foot roll of film 2% SINGLE CASE houses Cine-Voice camera, special amplifier unit, headphones, microphone and all cables. Total weight: 12V2 lbs. FOOTAGE METER', center; parallax corrected viewfinder, right, and two cable connections, left, are seen here on Cine-Voice. BOYNTON W. ROBERTS minutes of continuous recording, such as when picturing sports events. Single perforation sound films in black and white are offered by Ansco, DuPont and Eastman Kodak Company, while for full color shooting there is available either Daylight Type or Type A Kodachrome. All emulsions are on the familiar 100 foot daylight loading spool. To record actual sounds as they occur, along with the picture, the cameraman need only place the Cine-Voice microphone outside of camera range, adjust the amplifier and shoot. Synchronization of sound and picture is automatic, since both are put on the same film at the same time. Their separation is the ASA standard of twenty six frames between sound track and corresponding picture. Even if splices are made in the film, the sound and picture can be maintained in perfect synchronism. HOW SOUND IS RECORDED The sound track made by the Cine-Voice camera is of the variable area type and is recorded along the unperforated edge of the film by a galvanometer. This is an instrument having electric coils which move a tiny mirror in accordance with the sound waves being picked up by the microphone and amplifier. As this mirror swings back and forth, a beam of light is reflected from it onto the film, where it is recorded as a vibrating sound wave in photographic form. The galvanometer and all of the sound recording lenses are extremely rugged in construction and require no adjustment of any kind. Further, they will operate in any position, whether the camera is being hand held or is on a tripod. The galvanometer is driven from a five tube CineVoice amplifier, which has all the necessary controls for recording the highest quality of speech or music. The amplifier has two meters, one to indicate volume of sound being recorded on the film, and the other to indicate the exposure of the sound track. The meters are calibrated so that previous experience in sound recording is not needed to understand their use. The sound track exposure meter also provides a means of checking on the condition of the amplifier batteries, which are of the portable radio type and may be obtained at any radio supply store. INPUTS FOR MIKE AND PHONOGRAPH Two input plugs are provided on the CineVoice amplifier, one for the sound recording microphone and the second for connection to a crystal phonograph pickup. The microphone input has a volume control and also a speech-music tone control connected with it. The phonograph input allows you to feed music from phonograph records into the amplifier at the same time speech is being picked up by the microphone. Thus, both speech and music can be put on the film at the same time if desired. The amplifier has sufficient power to record speech satisfactorily when a person is talking in a normal tone of voice as far as six feet away from the microphone outdoors. [Continued on page 35J
