Abstract
M.I.T. Film/Video desired a computer controlled, Society of Motion Picture and Television Engineers (S.M.P.T.E.) standard compatible video editing and viewing environment for its movie laboratory. Such an environment would serve as a video workstation, providing means in the lab for computer driven manipulation of video information. Computers in the experimental workstation should readily connect to the computational resources in the M.I.T. community. An "open" system, then, supporting a variety of video and computational devices, would enable system expansion while best utilizing financial resources.

Various user interfaces to video information could receive attention in an experimental system. A hardware grant from the Asaca/Shibosoku Corporation promised an interesting user interface: 32 simultaneously displayed frames of video organized into four columns each holding eight frames; one to four columns gets input from one (of four total) video sources. This "multiview" mode contains a graphic audio signal display alongside the columns of frames. This multiview/audio graphic capability invites comparison to film image manipulation, a comparison that the experimental workstation will explore further.

having outlined research goals and acquired initial hardware for an "experimental video workstation," the focus became demonstration of its capabilities at the National Association of Broadcasters (N.A.B.) Convention in Dallas this past April. At the NAB convention exhibit, the experimental workstation would receive evaluation from the commercial broadcast community in the presence of the latest post production video systems.
