A shot is the basic unit of film and video editing. Editing is a way of creating meaning through the arranging and juxtaposition of sounds and images. Editing will determine the film's final length, emphasis, pacing and structure. The term normally refers to a series of shots taken in one location during a continuous or nearly continuous time. Dramatic films and some documentary films usually connect scenes in a way that may be hard for the casual observer to notice.
Feature films differ greatly in the number of scenes they contain.
More than one hundred is common. A sequence is one or more shots edited together to form a larger grammatical unit within a film. Many books on film contain outlines of film sequences. Where a particular sequence begins and where it ends may be decided by many different factors. For example, one viewer may think that a particular sequence began when an actor entered a room.
