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. [1]
Double-system recording is a form of sound recording used in motion picture production whereby the sound for a scene is recorded on a tape 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 ...
The method was then repeated for playback, but with the projectionist hand cranking the film projector. "Single-system" sound recorded sound optically to part of the original camera film, or magnetically to a stripe of magnetic coating along the film edge. [citation needed] "Double-system" sound used independent cameras and sound recorders. The ...
A sound follower to the left of a shadow telecine in the center of the image. Many motion picture cameras do not record audio sound on the film, so in professional film production, there is a need to have the sound recorded and played back on a device that has a double-system recording to tapes, or by any means, for example DAT or Nagra, SD or other audio recording media and then transferred ...
Prior to the introduction of 1/4-inch audio tape, recordings were made on 35mm optical cameras, and later on 16mm or 35mm magnetic stock. The first 1/4-inch recorder capable of recording a synch track to regulate the playback speed of the recording was made by Rangertone and was a variation on the soon-to-come Pilotone system.
Most film cameras do not record sound internally; instead, the sound is captured separately by a precision audio device (see double-system recording). The exceptions to this are the single-system news film cameras, which had either an optical—or later—magnetic recording head inside the camera. For optical recording, the film only had a ...
The first Dazzle recorder to support USB was the Digital Video Creator (DVC) 50 and 80 models, first released in March 2001. [8] [9] The DVC 80 was capable of recording both video and audio via RCA and S-video, while the more inexpensive DVC 50 was capable of recording only video. [10]
This system used a separate film for the sound, synchronized with the film carrying the picture. The sound film had four double-width optical soundtracks, three for left, center, and right audio—and a fourth as a control track with three recorded tones that controlled the playback volume of the three audio channels. Because of the complex ...
