Movie Mashups
Movie Mashups. A video mashup is the combination of multiple sources of video—which usually have no relation with each other—into 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 copyright law.
