This was one of the first NLE systems. It was the Montage Picture Processor and used 14 modified betamax VCRs as random access drives. You recorded your footage to all of the VCRs at one time and then as you edited it would access them as needed to playback your video. It had a lot of quirks but was quite advanced for its time. It was soon replaced by the Avid. It would generate an EDL that you would then take to a online edit suite and finish. This was strictly off-line draft quality. Now we can do it on a computer with a single harddrive at better quality and effects. If believe you could only create cuts but it might have allowed for dissolves. This was located at the company I worked for most of my career. This picture is from around 1986.
