It was also featured in Dario Argento's 1996 horror movie The Stendhal Syndrome (CGI, with a bullet) and the 1998 BBC documentary mini-series 'Intimate Universe: The Human Body'. The first example of bullet-time can be found in the obscure 1981 action film Kill and Kill Again. The same effect can also be produced using CGI and motion capture. This approach provides greater flexibility than a purely photographic one. Using sophisticated interpolation software, extra frames could be inserted to slow down the action further and improve the fluidity of the movement (especially the frame rate of the images) frames could also be dropped to speed up the action. Additionally, the individual frames were scanned for computer processing.

The cameras were then triggered at extremely close intervals, so the action continued to unfold, in extreme slow-motion, while the viewpoint moved. In The Matrix, the cameras were arranged on a track, forming a curve through space. The pictures in the still cameras are then displayed consecutively to produce an orbiting viewpoint of an action in hyper slow-motion. In film, the general effect is achieved by a set of still cameras surrounding the subject. It was previously referred to as time slice photography. It is often used to create a dramatic effect, and some variations involve rotating the camera view around the slowed-down scene. Bullet-time is a concept introduced in recent films and computer games whereby the passage of time is slowed down so that an observer can see individual bullets flying throughout the scene at a conceivable rate, usually with their trails made visible.
