Carol Vernallis developed a theory about music videos that focused on four key concepts: editing, narrative, diegesis, and camera movements/framing. She believed that editing in music videos is more frequent and draws attention through techniques like jump cuts. Narratives can be disjointed and incomplete as long as the song remains the focus. Diegesis refers to the world of the video that is revealed slowly through repetition of images with little sound. Camera movements often sync with the music and utilize close-ups and extreme shots to emphasize the performer.
