A video mashup (also written as video mash-up) is the combination of multiple sources of videos which usually have no relation with each other, other than a derivative work, often lampooning its component sources or another text. Many mashup videos are humorous movie trailer parodies, a later genre of mashups gaining much popularity. To the extent that mashups are 'transformative' of original content, they may find protection from copyright claims under the "fair use" doctrine of U.S. copyright law.
In 2007, a French internet user AMDS FILMS became worldwide famous with the mashup "Terminator vs Robocop", the chronicle of two giants of cinema. The first episode was seen over 30 million times around the world. Following this success, the director AMDS FILMS was contracted by major American studios.
Almost at the same time, internet users start to make video mash-ups by watching many YouTube videos simultaneously. Some of these have even become memes. One of the most famous is a guy filming himself swearing about some fat ladies in L.A. combined with an instrumental rap beat.
Supercuts have become a popular genre of video mashups. A "supercut" focuses on a specific word or element in a series of videos and remixes the multiple sources into one video montage. The "160 Greatest Arnold Schwarzenegger Quotes" supercut has over 12 million views on YouTube.
