Reflection on Genre Research

As i have been doing my main research for my Horror genre i have been able to learn various codes and conventions used within the genre of film which i intend to use thoroughly and correctly to create a successful trailer. Learning these aspects have helped me understand and gain a larger knowledge of the genre which will come helpful when producing my trailer. There are many aspects to consider when producing a trailer, especially when portraying the genre of the film;

The main location of my trailer would be focused within a family household or local country fields where i can play with various shots to get creepy effects. Due to focusing on a paranormal trailer i am fortunate to film within my own/friends living space - which allows me to not worry about budget fees. I am wanting to explore my local town to use different locations which can collaborate with a typical nuclear family household so i can gain different effects when editing.
As for my characters, i am wanting to include at least 3/4 cast member with an additional pet dog due to this creating a stereotypical nuclear family - which is my main aim within producing the trailer. I dont have a secure idea if i would prefer to make a teenage sleepover plot - this potentially could become unsuccessful or not filling the horror criteria to its best which can lead to it looking unprofessional and not appealing to watch whereas if i include an older generation of characters it can portray as a more serious matter to the narrative?
When concerning my costume and props, i am fortunate to allow my characters to wear their own clothes which adds to the realism of the plot. Having their own costumes allows them to portray their own character and persona on set which helps the audience interact with them. As with props, i wont need essential needs such as; weapons and fake blood, nevertheless, i will need to use props such as young plastic toys/dolls, swing set etc. I could potentially use a main prop as a marketing aspect which could become recognizable and known for my movie - such as using a swing set for my poster, magazine cover etc.
Having a successful soundtrack is probably a main element in creating a successful horror trailer, however due to my narrative, quietness is key when wanting to scare my audience due to them not expecting the following scene after. I will use a erry sound behind to create more of an atmosphere and heighten the tension whist watching the trailer. I will include effects such as crashes and door slams due to these sounds creating more of a fright for my audience, additionally, i will include heightened sounds of usual quiet sounds such as heartbeats and breathing to create tension.
