Editors use established techniques when cutting film trailers to provoke specific emotions and tell the story, such as using long shots to establish setting, fades to black to suggest shifts in time, and quick cuts of exciting moments. The music and sound effects are also carefully selected to build tension or highlight villains. For comedies, editors have more freedom with transitions to create a lighter tone. Voiceovers and text aim to communicate the unique selling point of the film and may reference established audiences, true stories, or star names to entice viewers. The language is chosen carefully to suggest key themes and summarize the complex plot in a dramatic way.
