The document discusses editing techniques used in movie trailers. It notes that horror movie trailers often use fast cuts of flashbacks to set mood. Trailers also use match cuts to show what characters are doing in scenes and cross-cutting to show simultaneous events in different locations. Pace is typically slow at the beginning of trailers and climactic at the end to build tension. Specific genres tend to use certain techniques: horror uses fast pace for jump scares; action uses CGI for special effects; spy films use inserts to show what characters see and slow motion for suspense. Inspiring techniques mentioned are fast pace for intrigue, slow motion used minimally, and inserts to provide context.
