History
- Before VTRs were invented, TV shows were recorded to film, for archive and later broadcast on a Kinescope.
- In 1967 CBS Laboratories introduced the Electronic Video Recording format, which used video and telecined-to-video film sources, which were then recorded with an electron-beam recorder at CBS' EVR mastering plant at the time to 35mm film stock in a rank of 4 strips on the film, which was then slit down to 4 8.75 mm film copies, for playback in an EVR player.
- All types of CRT recorders were (and still are) used for film recording. Some early examples used for computer-output recording were the 1954 IBM 740 CRT Recorder, and the 1962 Stromberg-Carlson SC-4020, the latter using a Charactron CRT for text and vector graphic output to either 16mm motion picture film, 16mm microfilm, or hard-copy paper output.
- Later 1970 and 80s-era recording to B&W (and color, with 3 separate exposures for red, green, and blue)) 16mm film was done with an EBR (Electron Beam Recorder), the most prominent examples made by 3M), for both video and COM (Computer Output Microfilm) applications.
- Image Transform in Universal City, California used specially modified 3M EBR film recorders that could perform color film-out recording on 16mm by exposing three 16mm frames in a row (one red, one green and one blue). The film was then printed to color 16mm or 35mm film. The video fed to the recorder could either be NTSC, PAL or SECAM. Later, Image Transform used specially modified VTRs to record 24 frame for their "Image Vision" system. The modified 1 inch type B videotape VTRs would record and play back 24frame video at 10 MHz bandwidth, at about twice the normal NTSC resolution. Modified 24fps 10 MHz Bosch Fernseh KCK-40 cameras were used on the set. This was a custom pre-HDTV video system. Image Transform had modified other gear for this process. At its peak, this system was used in the production of the film "Monty Python Live at the Hollywood Bowl" in 1982. This was the first major pre-digital intermediate post production using a Film recorder for film-out production.

Famous quotes containing the word history:
“As History stands, it is a sort of Chinese Play, without end and without lesson.”
—Henry Brooks Adams (1838–1918)
“There has never been in history another such culture as the Western civilization M a culture which has practiced the belief that the physical and social environment of man is subject to rational manipulation and that history is subject to the will and action of man; whereas central to the traditional cultures of the rivals of Western civilization, those of Africa and Asia, is a belief that it is environment that dominates man.”
—Ishmael Reed (b. 1938)
“We may pretend that we’re basically moral people who make mistakes, but the whole of history proves otherwise.”
—Terry Hands (b. 1941)
