Fast editing techniques like fast pace and jump cuts are commonly used in thriller and supernatural trailers to build tension and engage the target audience. Flashbacks may be included to provide backstory for characters. The pace typically starts moderate to introduce characters and the plot but increases during intense or scary scenes shown in a montage to create suspense. Editing styles vary by genre with techniques like fade to black transitions often used in horror. Non-linear narratives and use of sound effects are cited as effective techniques the author wishes to employ.
