In film and video editing, the term may refer to a “dissolve” (where one image gradually dissolves into, and is replaced by another) or to a “fade in” (where a blank screen gradually transitions to be replaced by an image or scene) or to a “fade out” (where an image or scene gradually transitions to be replaced by a blank screen). These may be used to create different effects (for example, the effect of time passing when used in a montage).
