Interactive video
From Wikipedia, the free encyclopedia
The term interactive video usually refers to a nowadays uncommon technique used to create computer games or interactive narratives. Instead of 3D computer graphics an interactive image flow is created using premade video clips, often produced by overlaying computer-generated material with 12-inch videodisc images (where the setup is known as "level III" interactive video, to distinguish it from "level I" or videodisc-only, and "level II" requiring specially made videodisc players that support handheld-remote based interactivity without using an external computer setup). The clips can be animation like in the video game Dragon's Lair or live action video like in the video game Night Trap. Technically VJing is also about creating a stream of video interactively.
Compared to other computer graphics techniques interactive video tends to emphasize the looks and movement of interactive characters instead of interactivity. Interactive video has been used in interactive cinema presentations. The addition of video as a media type to Flash has increased the use of interactive video in web design.
