In filmmaking and video production, footage is the raw, unedited material as it had been originally filmed by movie camera or recorded by a video camera which usually must be edited to create a motion picture, video clip, television show or similar completed work. More loosely, footage can also refer to all sequences used in film and video editing, such as special effects and archive material (for special cases of this, see stock footage and B roll). Since the term originates in film, footage is only used for recorded images, such as film stock, videotapes or digitized clips – on live television, the signals from video cameras are called sources instead.
