Codes and Conventions of the Horror Genre

Stereotypically, most horror films, like all films, follow a certain set of conventions throughout the genre, tailored for that genre in particular. For the horror genre, the main conventions are these:

• Low key lighting, giving a darker effect overall and enhancing things such as shadows
• Isolated locations for settings, this adds hugely to tension due to isolation of characters
• A female victim, this could be for sexual objectification or also to stick with stereotypes. It is unlikely that men would be seen as the main victims.
• A disruption of normality, creating a surreal look and unnerving the watcher as a result of this as it manipulates the concept of reality.
• Sub-plot of a male and female relationship to create another subject in the film. This is, more often than not, created mainly for female audiences, and also adds nicely to give more of a filling to the storyline to give more depth. 
• Defeat of monster of resolving of matter, this can help sculpt the film to create a happier ending after the whole ordeal of the issues going on during the film, usually created so the audience isn't left unhappy or unsatisfied with the film, and helps to still make the film some form of an enjoyable industry.

Although these conventions are used by many directors and creators, these conventions are often bypassed by others in the same position. From looking at this, I believe that I may break a lot of these conventions, and create something much different, which is a huge reason as to why I believe my trailer fits a more contemporary style so much more. 

Here is a very helpful source that I looked at for research:
