Filmstrip

1. A means of visual presentation, using a length of film with still images presented in sequence and projected onto a screen, similar to a slide show. The series may be accompanied by a recorded soundtrack, or a text for the presenter to read.

The most common film size used is 35 mm. Filmstrips with a soundtrack often include two versions: one with audible cues to indicate that the film should be advanced, and one with inaudible cues, for use with specially equipped projectors.

Owing to their simplicity, filmstrips were frequently used in educational settings, but they were largely overtaken in the 1980s by VCRs and the even simpler videocassette.

2.A length of photographic film. (Sometimes spelled film strip).

3. A computer graphic file format for animation sequences, containing multiple images with the same size. The format was introduced in Adobe Premiere.

A series of images on a strip of 35 mm film, just like you would use in a camera, uncut negatives. It worked like a slide film projector, lit by a bright bulb from behind, projecting the positive color image through a lens onto a surface, either a retractable classroom wall screen or the back of the viewscreen of a viewer. Some filmstrips came with a cassette or phonograph record that would beep when it was time for the operator to advance to the next image. Some viewers could advance the film automatically. Filmstrip topics ranged from culture and government to UFOs and crytopzoology. A student could view a filmstrip at a desktop viewer, similar to a microfilm reader, or a filmstrip could be projected on a screen in a classroom.
