Carol Vernallis developed a theory about key aspects of music video production including narrative, camera work, editing, and diegesis. The theory focuses on how the visuals of a music video relate to and enhance the lyrics. Specifically, Vernallis notes that establishing shots are important for setting the location, close-ups can show emotion, and editing techniques like jump cuts and pace changes can disrupt conventions. She also explains that the world of a music video, or diegesis, is gradually revealed through framing and repetition of certain shots.
