Abstract
Methods and apparatus provide for: recording a first 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, generating a second sequence of video images encoding the depth buffer value sequence, and associating the in-game virtual camera position sequence, with at least one of the first and second sequence of video images. Methods and apparatus also provide for: obtaining a first video recording of a videogame playing session comprising a sequence of video images, obtaining a second video recording generated by encoding a depth buffer value sequence, obtaining data indicative of an in-game virtual camera position sequence that is associated with at least one of the obtained video recordings, obtaining data indicative of a statistically significant in-game event and an in-game event position, calculating a position within a current video image of the first video recording corresponding to the in-game event position, in dependence upon the …
