Codes and conventions of music videos generally include style, camerawork, sound, mise-en-scene, editing, and stereotypes. However, these conventions can vary slightly depending on the genre and style of the video. Conventions create a structure for audiences to understand and familiarize themselves with different genres. Videos typically last the length of the song and represent the song's message through relatable themes. While most videos follow conventions, some challenge norms. The two main techniques used in videos are technical aspects like camerawork and symbolic elements like facial expressions.
