- CMX Systems
CMX Editing Systems (also known as CMX Systems) was a company founded jointly by
CBS andMemorex , that developed some of the very first computerized systems for linear and non-linear editing ofvideotape forpost production . The company's name, CMX, stood for CBS, Memorex, and eXperimental.Headquartered in
Sunnyvale, California , the company pioneered in integrating computers with videotape editing, starting in 1971 with theCMX 600 , the first non-linear video editing system. The 600 was designed primarily foroff-line editing , by creating both a rough edit of a video program, along with anedit decision list , or EDL. It stored its video & audio content ondisk pack drives supplied by Memorex for instant random access of the video content. The 600 was paired with the CMX-200, which took the edit decision list created by the 600, and automatically controlled severalVTR s to auto-assemble the final program. The 600 was controlled using a DigitalPDP-11 minicomputer, and the 200 used aTeletype modelASR-33 terminal to input EDLs from the 600.CMX also developed the CMX-300 in
1972 , a system used for on-line editing (and CMX's first on-line product). It was a computer-controlled linear editing system, with support up to four VTRs, and also included and controlled a simple video mixer for wipes and fades. The edits were input to the 300 (and displayed) using a DigitalVT-05 terminal.CMX would later develop more advanced systems such as the 340 in
1976 , and the CMX Edge, which could be used for both on and off-line editing.CMX was sold to
Orrox in 1974, and then moved its headquarters toSanta Clara, California . It was then later purchased by Chyron, and remained under its ownership until 1998, when Chyron announced that it would discontinue all CMX products.During the mid-1980s, CMX hardware consisted of 90% of all video editing systems used for post-production video editing.
The CMX keyboard control style was used as a basis of several other editing systems, including Grass Valley, Calaway and Strassner Editing Systems.
