If you’re a huge fan of movies, but you don’t know much about the technology that makes them possible, then we have the perfect informational video for you.
University of Illinois professor Bill Hammack, known as EngineerGuy on YouTube, has put together this informative video about how film projectors work. As the video description says:

He explains how all these mechanisms are synced.
