Westrex Film Editer
G. R. Crane, Fred Hauser, H. A. Manley · Journal of the Society of Motion Picture and Television Engineers · 1953
This paper describes a film-editing machine which employs continuous projection resulting in quiet operation. It accommodates standard-picture and photographic or magnetic sound film as well as composite sound-picture film. Differential synchronizing of sound and picture while running, automatic fast stop and simplified threading features in the film gates with finger-tip release materially increase operating efficiency.
