An anime music video (AMV) is a fan-made music video consisting of clips from one or more Japanese animated shows or movies set to an audio track, often songs or promotional trailer audio. The term is generally specific to Japanese anime, however, it can occasionally include footage from other mediums, such as American animation, live action, or video games. AMVs are not official music videos released by the musicians, they are fan compositions which synchronize edited video clips with an audio track. AMVs are most commonly posted and distributed over the Internet through AnimeMusicVideos.org, video downloads and YouTube. Anime conventions frequently run AMV contests who usually show the finalists/winner's AMVs.

Doujinshi (同人誌), also romanized as dōjinshi, is the Japanese term for self-published print works, such as magazines, manga, and novels. Part of a wider category of doujin (self-published) works, doujinshi are often derivative of existing works and created by amateurs, though some professional artists participate in order to publish material outside the regular industry.
