Music videos are short films that integrate song and imagery, primarily made to promote music sales. Early music videos from the 1920s included animated films set to music. Modern conventions include illustrative videos that tell stories, conceptual videos with abstract ideas, and amplification videos interpreting songs creatively. Music videos typically use shots like close-ups and long shots to establish artists and emotions, while camera movements follow artists or storylines. Elements like costumes, lighting, editing and more contribute to the overall mise-en-scene and presentation of the video.
