Pacing refers to the speed of cuts between shots in a film. Slow pacing is used for calm scenes like conversations, while fast pacing is used for intense scenes like car crashes. Computer generated imagery (CGI) is used to make things look more realistic, like rods piercing a car window and head. Shots over the shoulder are used to show connections between characters, like a mother and daughter's conversation lasting 3 seconds. Then the pacing and editing speed up with CGI during a crash scene.
