AMVs should not be confused with music videos that employ original, professionally made animation (such as numerous music videos for songs by Iron Maiden), or with such short music video films (such as Japanese duo Chage and Aska's song "On Your Mark" that was produced by the film company Studio Ghibli). AMVs should also not be confused with fan-made "general animation" videos using non-Japanese animated video sources like western cartoons, or with the practice of vidding in Western media fandom, which evolved convergently and has a distinct history and fan culture. Parallels can be drawn between AMVs and songvids, animated fan-made videos using footage from movies, television series, or other sources.
