Picture Music Video

A Picture Music Video is a type of video featuring little to no motion - PMVs are made mostly or entirely using still images. There may be a few short clips with normal motion, and the still images may be moved across the screen - the latter is known as tweening (derived from "between"), after the animation term used for when a computer gradually moves a drawing from one location to another, rather than an animator moving the image manually.

PMVs are created using either screenshots (modified or otherwise), fanart, or some combination of the two. Not all fan videos which use fanart are PMVs - the video has a lot of motion, it's not usually considered to be a Picture Music Video, which means that extremely dynamic and effect-heavy fanart-based videos typically don't count. PMVs without any motion whatsoever are sometimes simply referred to as slideshows. PMVs in the Homestuck fandom are often referred to as Lyricstucks, particularly if they are created using original artwork which incorporates song lyrics into the images.

Picture Music Videos are not to be confused with Pony Music Videos, although both are abbreviated as "PMV".

History
The earliest fanvids were PMVs made by using slide projectors to display frames of leftover film from Star Trek, and playing accompanying music using a cassette player. The first of these was What Do You Do With A Drunken Vulcan? by Kandy Fong.
