Conventions of Genres

Horror


In horror there are very distinctive sounds used in the back ground, like sudden low frequency trumpet sounds, crows, rain outside, and if there's allot of tension in the atmosphere, there may even be complete silence before a sudden, loud sound.
the film is often also set in an empty environment, like in the middle woods or the desert, or even in a small town away from the rest of civilization, so that the characters in the film cannot call police. There is also often a reason for them to not be able to leave the area, like there vehicles wont work, or they got in a car crash. The victims also get murdered when they are on their own, in a dark environment. The characters themselves tend to be young, students that go to the empty environment  on holiday with each other to basically take drugs, get drunk or to have sex.The being that's actually killing the victims is completely mysterious, an only near the end do you find out why its killing people. The killer also is always has its face hidden, and is mainly seen in darkness, your you cant see what it is, unless its a slasher horror, where the killer is in a specific outfit with a mask and a signature weapon.










Thriller


The thriller genre normally involves a main hero going through numerous deadly situations. The heroes of these films tend to be either men/women from a normal city or suburb with a normal life with no experience of action packed adventures, or professionals who are accustomed to danger, like policemen or criminals. In a typical thriller film, the hero attempts to defeat a main villain and to stop an evil plan or to solve a big mystery.
