Cutscene

A cutscene or event scene (sometimes in-game cinematic or in-game movie) is a sequence in a video game that is not interactive, breaking up the gameplay. Such scenes could be used to show conversations between characters, bring exposition to the player, set the mood, reward the player, introduce new gameplay elements, show the effects of a player's actions, create emotional connections, improve pacing or foreshadow future events.

Cutscenes often feature "on the fly" rendering, using the gameplay graphics to create scripted events. Cutscenes can also be pre-rendered computer graphics streamed from a video file. Pre-made videos used in video games (either during cutscenes or during the gameplay itself) are referred to as "full motion videos" or "FMVs". Cutscenes can also appear in other forms, such as a series of images or as plain text and audio.

Pac-Man—first released in 1980—is frequently credited as the first game to feature cut scenes, in the form of brief comical interludes about Pac-Man and Blinky chasing each other around during those interludes, though Space Invaders Part II employed a similar technique that same year.

In 1983, the laserdisc video game Bega's Battle introduced the use of animated full-motion video (FMV) cut scenes with voice acting to develop a story between the game's shooting stages, which would become the standard approach to video game storytelling years later. The 1984 game Karateka helped introduce the use of cut scenes to home computers. Other early video games known to make use of cut scenes as an extensive and integral part of the game include Portopia Renzoku Satsujin Jiken, and Bugaboo (The Flea) in 1983; Valis in 1986; Phantasy Star, Maniac Mansion, and La Abadía del Crimen in 1987; Ys II: Ancient Ys Vanished – The Final Chapter, and Prince of Persia and Zero Wing in 1989, with the poor translation in Zero Wing's opening cutscene giving rise to the (in)famous Internet meme "All your base are belong to us" in the 2000s. Since then, cutscenes have been part of many video games, especially in action-adventure and role-playing video games.
