Sprockets

Sprockets are the small “teeth” that fit into the perforations (or sprocket holes) that run along the edge of a film or mag. They are usually located on a spinning wheel in a projector, telecine, or other film playback/record machine. The sprockets drive the film forward by grabbing onto the sprocket holes at a regulated speed.
