How film projectors work

Thursday, July 9, 2015

Bill Hammack aka the Engineer Guy explains the mechanics of film projectors.
Bill tears apart a film projector to reveal the amazing mechanisms used in the pre-digital age to trick the mind into seeing a moving image. He uses high speed photography and animations to show how the projector moves the film intermittently, how a shutter strategically blocks light as the film moves, and how the photo sensor reads the sound. He explains how all these mechanisms are synced.
