Mashup (video)
A video mashup (also written as video mash-up) is a video that combines multiple pre-existing, unrelated video sources into one larger video. It is part of a global mashup culture.
In the United States, video mashups are derivative works as defined by the United States Copyright Act 17 U.S.C. § 101, and as such, they may find protection from copyright claims under the doctrine of fair use. Examples of mashup videos include movie trailer remixes, vids, YouTube poops, and supercuts.
