Speed/ style of editing

Film editing is the way in which editors can assemble their shots into a sequence and have them tell a story. The speed of the editing tells the audience how to feel. If a scene is longer than usual, it is so the audience can experience it for longer. In a thriller, longer scenes are used to build suspense and bring the audience in to eventually hit them with a jump scare. Similarly, faster editing is useful to speed up scenes and get the audience to the desired scene quicker.
