US Patent 11007436 Video recording and playback systems and methods

A method of detecting significant footage for recording from a videogame includes obtaining position information for a target object within a virtual environment of the videogame, obtaining depth buffer information for a current position of a virtual camera used to generate a current image of the virtual environment for display by the videogame, calculating a first distance along a line between the current position of the virtual camera and the obtained position of the target object, detecting whether a depth buffer value along the line corresponds to at least a threshold distance from the virtual camera, the threshold distance being based upon the calculated first distance, and if so, associating the current image with an indicator that the image is significant for the purposes of recording footage from the videogame.
