Fast cutting is a film editing technique which refers to several consecutive shots of a brief duration (e.g. 3 seconds or less). It can be used to quickly convey much information, or to imply either energy or chaos. Fast cutting is also frequently used when shooting dialogue between two or more characters, changing the viewer's perspective to either focus on the reaction of another character's dialog, or to bring to attention the non-verbal actions of the speaking character.

Hip hop montage
A hip hop montage is a subset of fast cutting used in film to portray a complex action through a rapid series of simple actions in fast motion, accompanied by sound effects. The technique was first given its name by Darren Aronofsky, who used the technique in his films Pi and Requiem for a Dream to portray drug use. According to the director's commentary of Requiem for a Dream, the hip hop montage is used in film as a sample is used in hip hop, with a few moments of film or video, respectively, repeated throughout the work for effect. The technique is derived from the hip hop culture of the 1990s and jump cuts first pioneered in the French new wave.
It was used earlier in Bob Fosse's All That Jazz and Paul Thomas Anderson's Boogie Nights. Guy Ritchie also used the technique in Snatch to portray transcontinental travel. The work of Edgar Wright, most notably in his collaboration with Simon Pegg (Spaced, Shaun of the Dead, Hot Fuzz, and The World's End) uses the technique for comedic effect.
