The system used an array of #Laserdiscs to store raw film footage. The players were linked to a control box that was controlled by a SUN Microsystems computer that allowed you to recall footage, make an edit decision list, it kept track of film frame numbers, and had many advanced features that allowed a classical film editor to use the system.
It interfaced with a jog shuttle knob to control the video.
