Fast paced editing is used to create a sense of urgency and build tension in films. Various editing techniques like jump cuts, cross cutting, cut aways, and match on action are employed to focus the audience on important plot points. Music and sound effects also play a role, with fast paced music building energy and sounds of clocks, footsteps, and violence adding realism and tension. Slower moments are sometimes incorporated to reflect low points for characters or build anticipation for key events.
