The document discusses different techniques used in music videos to amplify lyrics and music, including lip syncing, dancing, and editing. Lip syncing involves matching mouth movements to words and can be done for a music video or as part of a "diegetic" performance. Dancing to the beat is another simple way to amplify music. Editing techniques like fast cuts during intense parts of a song or slow motion during slower parts help match the video to the tempo and tone of the music. Examples of videos that employ these techniques are provided.
