Because a feature size film is so lengthy, distributors divide it into segments which might be rolled onto reels. A typical two-hour movie will in all probability be divided into five or six reels. Within the early days, films had been shown with two projectors. One projector was threaded with the primary reel and the opposite projector reduce energy consumption with the second reel of the film. The projectionist would begin the movie on the first projector, and when it was 11 seconds from the tip of the reel, a small circle flashed briefly in the corner of the display screen. This alerted the projectionist to get ready to vary to the opposite projector. Another small circle flashed when one second was left and the projectionist pressed a changeover pedal to start out the second projector and cease the primary one.
