This document outlines various technical codes and conventions commonly used in music videos. It provides examples of each convention from existing music videos to illustrate how they are employed. The conventions discussed include slow motion, camera movement, different locations, close-ups, rhythmic editing, diegetic/non-diegetic lighting, walking while singing, moving lights, and pulled focus. Specific music videos are analyzed such as "Slow Motion" by Trez Songs and "Hello" by Adele to demonstrate how the conventions enhance the themes and moods conveyed in the songs.
