Trade name (used generically) for an upright film editing machine common in the U.S., containing a mono speaker. The term is often applied to any type of viewing and/or editing machine that runs picture and sound interlocked in sync. It is used by the film editor to decide which parts of specific takes of specific scenes will be used in the workprint. The film and soundtracksound tracks may run vertically on an upright Moviola (old-style) or horizontally on a flatbed version. All of these have been gradually replaced by digital audio workstations.
