The cabin in the woods this film was released in 2012, the opening of the trailer introduces the audience to the main characters and straight away to what the problem is going to be, there is also a birds eye view shot and a couple point of view shots.by having a large a lot of establishing shots it helps to make audience feel as if they are involved in the movie. The shot of a control room soon creates an uneasy atmosphere for the audience and enhances the horror genre.

The camera work in this trailer is used to show the emotion and reactions on the characters faces as the story unfolds and they see the trap that they have been led into, they use a lot of close up and medium shots and birds eye view in the trailer to first establish the setting then show the sequence, it helps the audience to gain a personal connection with the characters but also make them feel slightly uncomfortable. Towards the end of the trailer they have used the quick cutting editing technique which is not unusual when it comes to horror genre films, the fast cutting helps to create tension and excitement from the viewers it will encourage them to go and view the movie, they have edited the trailer so they show the most exciting scenes and also having multiple shots of a black screen with red text on it, by doing this it makes the user question what they have just seen, also the use of red is also a sign of danger.

Also in the trailer there is non-diegetic sound put over all the action going on in the different sense this makes it seem like the people are not alone in the cabin and that somebody is watching them, because of all the rhetorical questions that are being asked which is adding to the tension that the audience is already feeling. The diegetic sound in this trailer starts with the characters in car sounding optimistic and happy but eventually they start to sound plagued with fear, the sounds of horror fright start to fill the ears of the viewers.
