The document discusses techniques used in a trailer to build tension and highlight weaknesses of the main characters. It focuses on using young female characters who are portrayed as weaker and needing saving. Dynamic music is used, including heavy breathing and increased heartbeats to suggest panic and tension. Video clips are sped up and reversed, adding confusion and a sense that the characters' fate is already decided. The dense woodland setting is stereotypically associated with danger. A voiceover was avoided to not distract from the visuals and dynamic sound effects.
