This document provides an overview and analysis of four film trailer structures and conventions. It summarizes each trailer's key elements, including opening logos, establishing shots, voiceovers, editing techniques, lighting, costumes, and character types. Common conventions identified across the trailers include fast pacing to depict fun/partying that contrasts with later tension; isolated settings; portrayals of "slutty" victims and tougher final girls; and the use of jumps scares, intense sounds, and lighting to build suspense. The document aims to understand effective trailer design to help create its own slasher trailer.
