Single-system Recording
Single system audio is the system of recording ''sound on film'' or ''SOF''. There are two methods of recording, the older method, optical and the later method, magnetic. SOF was primarily used for news film prior to the advent of portable videotape recording, but was used until recently for documentary film recording. Optical For Optical recording, the film only had a single perforation and the area where the other set of perforations would have been was exposed to a small bright lamp inside the camera controlled by an amplifier (usually in a separate box) that would vary the area of recording (RCA type), by means of shutters pulled back by variation in current, or variations in intensity (Western Electric type). Editing involved painting or taping over the optical track for the distance the sound led the film through the camera and projector. This would avoid the popping sound, but would result in a second of silence. Magnetic Magnetic recording had magnetic media in the area wh ...

Western Electric
The Western Electric Company was an American electrical engineering and manufacturing company officially founded in 1869. A wholly owned subsidiary of American Telephone & Telegraph for most of its lifespan, it served as the primary equipment manufacturer, supplier, and purchasing agent for the Bell System from 1881 to 1984 when it was dismantled. The company was responsible for many technological innovations as well as developments in industrial management. History In 1856, George Shawk, a craftsman and telegraph maker, purchased an electrical engineering business in Cleveland, Ohio. In January, 1869, Shawk had partnered with Enos M. Barton in the former Western Union repair shop of Cleveland, to manufacture burglar, fire alarms, and other electrical items. Both men were former Western Union employees. Shawk, was the Cleveland shop foreman and Barton, was a Rochester, New York telegrapher. During this Shawk and Barton partnership, one customer was an inventor sourcing parts an ...

Auricon
Auricon cameras were 16 mm film Single System sound-on-film motion picture cameras manufactured in the 1940s through the early 1980s. Auricon cameras are notable because they record sound directly onto an optical or magnetic track on the same film as the image is photographed on, thus eliminating the need for a separate audio recorder. The camera preceded ENG video cameras as the main AV tool of television news gathering due to its portability–and relatively quick production turn-around–where processed negative film image could be broadcast by electronically creating a positive image. Additionally, the Auricon found studio use as a 'kinescope' camera of live video off of a TV screen, but only on early pre-NTSC line-locked monochrome systems. Auricon cameras were used primarily by news and documentary filmmakers. They had also found favor with independent and experimental filmmakers such as Paul Morrissey because of their ability to record long takes with sound on film. Eventua ...

Cinema Products Corporation
Cinema Products Corporation was an American manufacturer of motion picture camera equipment. History The company was formed in 1968 by Ed DiGiulio, a former director and vice-president of the Mitchell Camera Corporation. Their first product was a Silent Pellicle Reflex conversion of the Mitchell BNC 35 mm Motion picture camera. The company expanded into the 16-millimeter news camera market with the introduction of the CP-16. The CP16 was based on the film advance mechanism used in the older " Bach-Auricon" sound-on-film cameras, but reconfigured in a lighter, more ergonomic self-blimped body configuration. It became one of the most widely used sound-on-film cameras in the TV news industry until it began to be superseded by the color professional video formats of the late 1970s.

Double-system Recording
Double-system recording is a form of sound recording used in motion picture production whereby the sound for a scene is recorded on a machine that is separate from the camera or picture-recording apparatus. Double-system recording is the standard procedure on motion pictures that are originally photographed on film. Recording sound-on-film directly at the time of photography has several technical limitations, and no professional motion picture camera supports this option, so all production sound is recorded on a separate recorder. This procedure requires that both camera and sound recorder share a very accurate time reference, and that the speed of the camera and sound recorders be carefully governed. Originally this was done with an electro-mechanical interlock between the camera and recorder, necessitating a physical link, a cable, between recorder and camera. As quartz-based timers came into common use, film cameras and sound recorders adopted these, and these were accurat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
