Andrew Goodwin identified 5 key aspects of music videos: 1) Through a beat, where visuals are edited to the music's tempo and lyrics, 2) The relationship between visuals and the song's meaning, 3) A narrative and artist performance to engage viewers, 4) Technical elements like camera work and editing that create atmosphere, and 5) The star image to promote the artist visually. Goodwin believed these elements were important for a music video's success.
