Animated Viewer
An animated viewer is a piece of equipment used in traditional film editing. The term describes a machine that allows an editor to view a motion picture for examination during the editing process. These viewers provided a larger, clearer moving picture than simple, hand-cranked devices. This enabled a more detailed analysis of the film. While “animated viewer” is a descriptive term, this type of machine is more commonly known by specific brand names, like Moviola or Steenbeck, or by the general category name, flatbed editor.

The Film Editor’s Workstation
Before digital technology, film editors worked with physical film prints. They could not simply drag and drop clips on a computer timeline. Instead, they needed a machine to play, analyze, and mark the film. The animated viewer became the editor’s primary workstation. It allowed them to watch scenes in real-time, shuttle forwards and backward, and listen to synchronized sound. This equipment was the heart of the cutting room for most of the 20th century. It was an essential tool for crafting a film’s final narrative.
How Animated Viewers Work
There were two main types of animated viewers.
| Upright Viewers (Moviola) | The Moviola was an early and iconic upright editing machine. An editor would sit in front of it and look down into a small, magnified viewing window. The film was threaded through a series of rollers and gates. The editor used foot pedals to control the speed and direction of the film. A separate sound head played audio from a synchronized magnetic film track. The Moviola was loud and somewhat cumbersome. However, it gave editors precise frame-by-frame control. |
| Flatbed Editors (Steenbeck) | In the 1960s, the flatbed editor became more popular. Brands like Steenbeck and KEM were industry standards. A flatbed has a large, horizontal table-like surface. The editor would load platters of film and magnetic sound onto the machine. The image was projected onto a central viewing screen. Flatbed editors were much quieter and gentler on the film print than a Moviola. They also made it easier to manage multiple sound tracks simultaneously. |
The Physical Editing Process
The editing process on these machines was a tactile, physical craft. An editor would watch a take on the viewer. When they found the exact frame where they wanted to make a cut, they would stop the machine. They would then mark the celluloid directly with a grease pencil. Next, they would remove the film from the viewer. They used a machine called a splicer to cut the film at the marked point. Finally, they would physically join the desired shots together using clear adhesive tape or film cement. This process of viewing, marking, cutting, and splicing was repeated for every single edit in the movie.
The Digital Revolution
Today, non-linear editing (NLE) systems like Avid Media Composer or Adobe Premiere Pro have replaced animated viewers. The physical craft of splicing film has given way to the digital process of editing video files. Modern digital workflows are non-destructive. They offer incredible speed and flexibility. However, the fundamental principles of editing—timing, pacing, and visual storytelling—were perfected by generations of editors working on Moviolas and flatbed viewers.
