This document discusses concepts of time in cinema. It begins by explaining that film is inherently a time-based medium structured around duration. Filmmakers use techniques like temporal markers and editing to manipulate the experience and flow of time. Early films by the Lumière brothers and Alice Guy Blaché explored the discoveries of capturing time through a motion picture. There are different types of time in film including scene time, duration, and simultaneous time. Exercises are proposed to experiment with capturing the passage of time through long takes, cuts, and transformations over the duration of a shot.
