Telerecording


Kinescope /ˈkɪnskp/, shortened to kine /ˈkɪn/, also known as telerecording in Britain, is a recording of a television program on motion picture film, directly through a lens focused on the screen of a video monitor. The process was pioneered during the 1940s for the preservation, re-broadcasting and sale of television programmes before the use of commercial broadcast-quality videotape became prevalent for these purposes.

Typically, the term can refer to the process itself, the equipment used for the procedure (a 16 mm or 35 mm movie camera mounted in front of a video monitor, and synchronized to the monitor's scanning rate), or a film made using the process. Kinescopes were the only practical way to preserve live television broadcasts prior to the introduction of videotape in 1956. A small number of theatrically released feature films have also been produced as kinescopes.

The term kinescope originally referred to the cathode ray tube used in television receivers, as named by inventor Vladimir K. Zworykin in 1929. Hence, the recordings were known in full as kinescope films or kinescope recordings.  RCA was granted a trademark for the term (for its cathode ray tube) in 1932; it voluntarily released the term to the public domain in 1950.
