Carol Vernalis' theory of music videos focuses on four key concepts: narrative, editing, camera movement, and diegesis. The narrative of a music video may be partial or disjointed and reflect the lyrics being sung. Vernallis also believes music video editing often breaks conventions through techniques like jump cuts and ignoring continuity rules. Camera movements in music videos frequently include establishing shots, close-ups, and movements that match the lyrics. Finally, diegesis refers to the world of the music video and its narrative, which is often revealed slowly through certain emphasized frames.
