Music videos can be categorized into 5 main types: performance, narrative, cameo, animation, and mixture. Each category uses certain film techniques and conventions. Performance videos mainly feature the artist singing and sometimes include dance routines. Narrative videos tell a story through scenes and lyrics. Cameo videos include the artist in another storyline. Animation can be digital or stop-motion. Mixture combines performance and narrative elements. Techniques like camera shots, editing, sound, and mise-en-scene vary based on the category to effectively promote the song.
