The conventions of a music video include featuring the artist or band. Shots are usually close ups, mid shots, and long shots to show emotion, scenery, and actions like playing instruments or dancing. The mise-en-scene varies by genre - rock videos often show live performances while R&B features dancing and crisp outfits. Music videos use editing techniques like jump cuts and dissolves. The purpose is to promote the artist's song and help audiences understand the song's meaning. There are three main types of music videos: concept-based use obscure ideas, performance-based feature the artist performing, and narrative-based tell a story.
