A Video Synthesizer is a device that electronically creates a video signal.
A video synthesizer is able to generate a variety of visual material without camera input through the use of internal video pattern generators, as seen in the stillframes of motion sequences shown above. It can also accept and "clean up and enhance" or "distort" live television camera imagery. The synthesizer creates a wide range of imagery through purely electronic manipulations. This imagery is visible within the output video signal when this signal is displayed. The output video signal can be viewed on a wide range of conventional video equipment, such as TV monitors, theater video projectors, computer displays, etc.
Video pattern generators may produce static or moving or evolving imagery. Examples include geometric patterns ( in 2D or 3D ), subtitle text characters in a particular font, or weather maps.
Imagery from TV cameras can be altered in color or geometrically scaled, tilted, wrapped around objects, and otherwise manipulated.
A particular video synthesizer will offer a subset of possible effects.

Famous quotes containing the word video:
“These people figured video was the Lord’s preferred means of communicating, the screen itself a kind of perpetually burning bush. “He’s in the de-tails,” Sublett had said once. “You gotta watch for Him close.””
—William Gibson (b. 1948)
