What is Dissolve: Definition and 55 Discussions

In the post-production process of film editing and video editing, a dissolve (sometimes called a lap dissolve) is a gradual transition from one image to another. The terms fade-out (also called fade to black) and fade-in are used to describe a transition to and from a blank image. This is in contrast to a cut where there is no such transition. A dissolve overlaps two shots for the duration of the effect, usually at the end of one scene and the beginning of the next, but may be used in montage sequences also. Generally, but not always, the use of a dissolve is held to indicate that a period of time has passed between the two scenes. Also, it may indicate a change of location or the start of a flashback.
