Film Gate, circa 1895
01
Artifact Overview
A Geneva or Maltese cross movement is a mechanical gear system that transforms a continuous rotating movement into a stepped movement. While the illusion is that the film in a movie projector is running past the lens in a steady stream, each frame must stop for 1/24 of a second in front of the lens. Geneva movements allow this conversion.
