A border created while one video image is ins erted in to a designated area in another (in a circle, rectangle or almost any other shape) by using a special effects generator or another keyer. This border between the two images can vary from a sharp line to a vague blending of images between the two pictures. One of the features in special effects generators is picture border (edge) control. It allows the user to control both the color and the sharpness or fuzziness (softness) of the border between the two images.
