This document discusses the conventions and techniques used in music videos. It explains that music videos can feature artists lip syncing and performing, narratives acting out the song's meaning, or mixtures of both. Editing must sync the audio and video accurately. Parody videos humorously change original songs' lyrics and sometimes reference the original's video. Weird Al Yankovic is famous for parody songs and sometimes references original videos. Other parody artists on YouTube use acting, animation, and performance to match changed lyrics.
