'Grave Encounters' - Trailer Deconstruction

Point 1: Introduction
Camera Angles/Shots/Movements: Canted framing in image two, the ground looks uneven. This gives the idea that something isn't quite right. Camera is shaky in image 2 as they get ready telling us that it is a hand held camera and they don't have a really big crew with them therefore there aren't going to be that many people within the hospital. Also telling us that this footage which hasn't been edited and therefore we are getting everything that actually happened without any hidden bits.
Editing: Many jump cuts and 'problems' within the film for example the screen having sections of it not matching up to the rest of the screen which could link in with demonic/spiritual effects on technology.
Sound: Sound of film whirring, discordant and high, uncomfortable to listen to and sets the audience on edge, non diegetic (the crew would not have heard that) telling us that they are oblivious to what is going to happen to them and that they are oblivious to the spiritual connection they are already experiencing (or the audience is already experiencing) the demons/spirits have already got them.
Mise En Scene: Green background linking in with supernatural and illness (connection to the hospital) both the man and the woman is wearing black foreshadowing their sufferings in the future. Black and white diagonal stripes: foils for each other, makes the white stand out among all the black in the first image which could emphasize the innocence the crew have before entering the hospital and the fact that they have no clue about whats going to happen to them.


Point 2: Abandoned Hospital 'intro'

Camera Angles/Shots/Movements: Establishing shot, makes the building look imposing and very large, easy to get lost in. Eye level shot on image 3 making the audience experience what it must be like in the hospital and creating a sense of fear. Camera pans along the room slowly in the second image which builds the tension as you cannot see around the room properly so it builds tension.
Editing: Jump cuts of different clips of the hospital giving the audience a feel of how big the hospital is and how easy it is to get lost in it. This method also shows no proper link between the rooms, they could be anywhere scattered around the hospital so the audience doesn't get to know the area.  
Sound: Different eye witnesses or janitors of the hospital narrating over the top or telling their stories giving the clip a more documentary type feel which are made on true stories therefore making it out as if this story is real.
Mise En Scene: Vertical lines are shown symbolising the building's strength and the fact that it cannot be beaten. A green hue to the images/clips of the hospital linking it to the supernatural. Lots of darkness symbolising evil and suffering (gives a foreboding sense)

Point 3: Old Clips (mental patients) 

Camera Angles/Shots/Movements: Zooming in on the patients we are meant to focus on, high angles of the patients showing their vulnerability and giving the idea that the mental asylum wasn't there to help them just to lock them away (which emphasises what is said in the narration)
Editing: Black and white, foils for each other which could show evil and purity/innocence. Could also emphasise it was a while back, making it more realistic for the audience. Simple font links more to the factual than the made up and extravagant so the fact that it is very simple makes it seem more realistic as well.
Sound: Different accounts of what happened in the hospital, what the patients were like, how they were treated. Once again linking to the documentary side, telling the audience that this was real.
Mise En Scene: Watching a static television suggests being cut off from the world, he isn't being connected with the outside, they were just locked away and forgotten about. Darkness gives the impression that there was no light in that place and the camera lights are the only lights there so once again they were shut off and left un-cared for.



Point 4: Ending


Camera Angles/Shots/Movements: Hand held camera, they are alone. Long shot of the woman giving the audience distance and making them feel safe until it zooms in a lot on the woman's head as she turns creating a sense of unease.
Editing: Face morphs, eyes and mouth are very dark. Eyes are meant to be the innocent and child like part of a human so the fact that they have been infected by the darkness suggests that this person is truly evil. Mouth is dark which could tell us that first of all the whole of the inside of the person is evil, but maybe also that she will infect other people.
Sound: It goes silent when the woman is found in the corner of the room creating suspense and building tension. Then when she screams everyone screams along and the music becomes dramatic and loud, probably having the jump factor and making the trailer scary. Sound building up to this sounds like a camera flash sound which is uncomfortable to hear and very high (could link to frequency, what is real and what is not? Are spirits and the supernatural there, but we cannot hear them because they are too high a frequency for example?)
Mise En Scene: Greeny hue, once again linking to the supernatural. Darkness/black = evil and suffering. Checkered tiles tell us that there is something not right with this, a dirtied (once white) hospital gown suggests infection and links with innocence being tainted by the hospital. Perhaps the fact that this dirty gown is on her could suggest that it's the hospital that made her like this, not herself.
