Sound research

To make an effective trailer the sound has to match the action that is seen on scene and portray the tone of the film. This is especially important in trailers as it is the first glimpse an audience will see, so it has to work well enough that the audience want to see more.  

I was inspired by the sound in another psychological film stoker. What I like about this was the chilling tone of voice at the beginning of the trial and the use of the monotonous sound of the metronome and that when it stopped the pace of the editing increased to build tension.

Another film I was inspired by was moments. I thought that the camera flashes and the steady build up of tension.


To create effective sound on our trailer I looked for a website which contained royalty free music that we could use and found a website called incompetech which had a large amount of baking tracks to use. I put in the characteristics that would work well for our teaser trailer and downloaded some appropriate tracks that we could possibly use.




















 I then layered the appropriate tracks over each other so that we could have the most effective sound. I had to cut them and use a number of different tracks over one another so that we could get our desired sound.

We still weren't happy with our sound so I decided to include some sounds of a camera flashing when the images of the polaroids came up.

We also included a voice over which explained the narrative of the film without relying on actors as this can sometimes make it look armature.







We also decided to include some booms in when the killer is being shown to build tension and to

convey to the audience that he is intimidating, this pared with the low angle shot will convey the protagonists fear.








At the end we wanted it to be quite chilling and

so we put a loud high pitch ringing noise which you get after a dramatic event such as a car crash so that the audience felt like they were being abducted.
