Video Editing - History
The first truly non-linear editor, the CMX 600 [1], was made in the early 1970s by the CMX Corporation (a joint venture between CBS and Memorex). It recorded & played back black-and-white video recorded in analog in "skip-field" mode on modified disk pack drives the size of washing machines (which were more commonly used with storing data on mainframe computers of the time). The 600 had a console with 2 monitors built in, with the editor making cuts and edit decisions using a light pen to select options suprerimposed as text over the preview video on the right monitor (the left monitor was used to display the edited video). A Digital PDP-11 computer served as a controller for the whole system. Because the video edited on the 600 was in black and white and in low-resolution "skip-field" mode, the 600 was suitable only for offline editing.Various approximations of non linear were built in the 80's using computers coordinating multiple laser discs, or banks of VCRs. Computer processing advanced sufficiently by the late 80's to enable true digital imagery, and has progressed today to provide this capability in software on personal computers. (more)
