Choosing suitable scenes is vital, yet it’s common for editors to misstep by selecting scenes that lack impact or don’t align with the trailer's narrative arc. Including too many mundane or disconnected scenes can weaken the trailer’s ability to excite or inform viewers. Editors should focus on scenes that best represent the film's highlights and emotional core. Another mistake is using spoilers or pivotal plot points that give away too much. Careful curation avoids revealing too much while maintaining intrigue. Correcting these common mistakes ensures a trailer that teases effectively and leaves viewers wanting more.
