Editing

CUTS - this is probably the simplest editing technique and also the most effective. Cuts are used to keep the audiences attention by moving from one viewpoint to another. This is because if the film//trailer constantly stayed in one viewpoint then the audience would get bored. There are a few different cuts that can be very effective in a horror film. The first one is a jump cut where the camera quickly cuts from one thing quickly to create a dramatic point.

Jump Cut Examples

The cutting rhythm indicates the speed in which the scenes are cut and can be quite a main factor in making a film a horror. If the cutting rhythm is quick and frequent then this helps install fear and suspense into the audience.

Quick Cutting Rhythm Example

Then there are things such as cross cutting, parallel editing and a cutaway shot.

CAMERA MOVEMENT - Sometimes in a horror film you will find that the camera movement seem to be very still during the calm parts and suddenly much more energetic around the scary parts. This causes the audience to react as they get used to the normal camera movements so the more energetic movements around the horror parts unsettle the audience causing them to feel fear along with the film.
