This document summarizes the use of conventions and techniques in the construction of a film trailer. It discusses how the trailer follows conventions like building tension through changing editing speeds from slow to fast. It establishes a hero/villain distinction through clothing. It builds tension in editing by starting slow and becoming faster as the "equilibrium breaks." Music and selective shots are used to create an atmospheric and tense feeling. While most thriller trailers are mysterious, this one reveals more of the plot to explain it. New media like digital cameras, editing software, blogs, and photo manipulation were used in planning, research, and presenting the project.
