The opening sequence of the film Titanic uses non-diegetic music to set a melancholy tone despite scenes showing happy people waving goodbye on the ship and on land. Shots are edited to look like old footage or memories. Transitions between shots use cross fades to smoothly flow between scenes without interrupting the joyous expressions and body language. The title 'TITANIC' is prominently displayed over a reflection of the deep blue sea, which then transitions to diegetic sounds of a submarine nearing the surface accompanied by beeping location sounds. The non-diegetic music continues until the submarine is almost out of sight, concluding the first two minutes of the film.
