In film, a match cut is a cut from one shot to another where the two shots are matched by the action or subject and subject matter. For example, in a duel a shot can go from a long shot on both contestants via a cut to a medium closeup shot of one of the duellists. The cut matches the two shots and is consistent with the logic of the action. This is a standard practice in Hollywood film-making, to produce a seamless reality-effect.
Match cuts form the basis for continuity editing, such as the ubiquitous use of match on action. Continuity editing smooths over the inherent discontinuity of shot changes to establish a logical coherence between shots. Even within continuity editing, though, the match cut is a contrast both with cross-cutting between actions in two different locations that are occurring simultaneously, and with parallel editing, which draws parallels or contrasts between two different time-space locations.
A graphic match (as opposed to a graphic contrast or collision) occurs when the shapes, colors and/or overall movement of two shots match in composition, either within a scene or, especially, across a transition between two scenes. Indeed, rather than the seamless cuts of continuity editing within a scene, the term "graphic match" usually denotes a more conspicuous transition between (or comparison of) two shots via pictorial elements. A match cut often involves a graphic match, a smooth transition between scenes and an element of metaphorical (or at least meaningful) comparison between elements in both shots.
A match cut contrasts with the conspicuous and abrupt discontinuity of a jump cut.
Stanley Kubrick's 2001: A Space Odyssey contains a famous example of a match cut. After an ape discovers the use of bones as a tool and a weapon, he throws one triumphantly into the air. As the bone spins in the air, there is a match cut to a much more advanced tool: an orbiting satellite. The match cut helps draw a connection between the two objects as exemplars of primitive and advanced tools respectively, and serves as a neat summary of humanity's technological advancement up to that point. The satellite is unidentified in the film, but the novel makes it clear that it is an orbital weapon platform, thus linking with the use of the bone as a weapon.
Michael Powell and Emeric Pressburger's A Canterbury Tale is a predecessor for the 2001: A Space Odyssey match cut in which a fourteenth-century falcon cuts to a World War II aeroplane. The sense of time passing but nothing changing is emphasised by having the same actor, in different costumes, looking at both the falcon and the aeroplane.
