The document discusses the use of conventions in the creation of a trailer for a media production project. It summarizes that the trailer borrows conventions from other thriller trailers, such as using dark lighting when the female character is held hostage. It also challenges some conventions, like starting the trailer with a calm scene rather than immediate suspense. Editing techniques like jump cuts and fast pacing were used to build suspense. Camera shots focused on characters' emotions. Mise-en-scene established settings and used props and clothing relevant to the storyline. Sound also helped build tension throughout the trailer.
