Telecine
With the advent of television, broadcasters quickly realized the limitations of live television broadcasts and they turned to broadcasting feature films from release prints directly from a telecine. This was in the days before 1956 when Ampex introduced the first Quadruplex videotape recorder (VTR) VRX-1000. Live television shows could also be recorded to film and aired at different times in different time zones by filming a video monitor. The heart of this system was the kinescope, a device for recording a television broadcast to film.
The early telecine hardware was the "film chain" for broadcasting from film and utilized a film projector connected to a video camera. As explained by Jay Holben in American Cinematographer Magazine, "The telecine didn't truly become a viable post-production tool until it was given the ability to perform colour correction on a video signal."
Today, telecine is synonymous with colour timing as tools and technologies have advanced to make colour timing (colour correction) ubiquitous in a video environment.
