The document analyzes conventions used in horror movie trailers to establish genre and create tension for the audience. Trailers typically frame shots in a way that leaves parts unclear, use camera shakes to disorient viewers, and cut shots short to build mystery without providing full context. Editing increases pace and uses shorter cuts to transform a sense of normalcy into one of threat. Sound design employs tension-building techniques like repetitive clocks and startling stingers. Settings aim for realism to make the content seem genuinely frightening. Color palettes and roles for male and female characters also adhere to horror conventions. Effective trailers employ these techniques to hook audiences through an escalating sense of tension, mystery and threat.
