Abstract
A video effects generator consists of two major components: an electronic video switch and a waveform generator. The switch can give either sharp or soft edges, fade in or out or fade bewteen the two inputs. This switch is driven by a waveform generator to provide switching at a line rate, field rate or both. Effects result when two video sources are alternately selected within the time of one field.
