Abstract
A video recording method includes recording a sequence of video images output by a videogame, recording a sequence of depth buffer values for a depth buffer used by the videogame, recording a sequence of in-game virtual camera positions used to generate the video images, recording one or more in-game events and their respective in-game positions, associating the depth buffer value sequence, the in-game virtual camera position sequence, and an identifier for the videogame, with the video image sequence, and associating the one or more in-game events and their respective in-game positions with the identifier for the videogame. A video playback method includes obtaining a video recording of a videogame playing session, comprising a sequence of video images, obtaining a depth buffer value sequence, an in-game virtual camera position sequence, and an identifier for the videogame that are associated with the video recording, obtaining data indicative of a statistically significant in-game event and an in-game event position, calculating a position within the current video image corresponding to the in-game event position, in dependence upon the associated in-game virtual camera position …
