AMVs are not official music videos released by the musicians, but are rather amateur fan compositions which synchronize video clips with an audio track. AMVs are most commonly informally released, most often over the Internet. Anime conventions frequently run AMV contests or AMV exhibitions. While AMVs traditionally use footage taken from anime, video game cut-scene footage is also a popular option. Music used in AMVs is extremely diverse, using such genres as J-Pop, rock, hip hop, pop, R&B, country, and many others.
