Genre Conventions

From analysing trailers and a full length film, i have discovered the following about mystery film trailer conventions:

• Low-key lighting is used to connote a sense of mystery and eeriness.
• Close-ups and extreme close-ups are used very frequently to allow the audience to connect with the main characters and also to allow them to see the panicked, scared facial expressions on them, therefore convey a sense of mystery.
• High angle shots are effective in making the characters appear weak and vulnerable, therefore in danger.
• The use of long shots allows the audience to become familiar with the setting of the film and understand the dynamic between characters.
• It is effective to use a slower pace of editing at the beginning of the trailer and build to a faster pace of editing during disequilibrium as this connotes panic and franticness. 
• A dramatic, fast pace score successfully builds tension and creates momentum throughout the trailer.
• The use of foley is effective as it accentuates important elements in the trailer.
