The Mechanics of Film Projector

The Mechanics of Film Projector

Film used to be everything, and the optical illusion of movement by projecting frames of film via light is monumentally important to the advancement of visual entertainment. In this video Bill, engineerguy, 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. If you ever wondered exactly how all the individual pieces work together and sync up, then this is for you. Heck, even if you're just a fan of "How It's Made," you'll love this.
