The average shot length (ASL) of a film is one of its cinemetrical measures. For example, The Mist has a length of 117 minutes and consists of 1292 shots, so the ASL is 5.4 seconds. In film, a shot is a continuous strip of motion picture film, created of a series of frames, that runs for an uninterrupted period of time. Shots are generally filmed with a single camera and can be of any duration. Frames, shots, scenes, and sequences form a hierarchy of units fundamental to many tasks in the creation of moving-image works.
