Research into Radio Trailers

Conventions of a radio trailer:

• voice over with hints of sound/speech from the film
• information at the end of the trailer, stating viewing date and certificate
• the slogan for the film
• sound effects when appropriate
• the purpose which is to persuade various specific audiences to watch the film/programme 

Radio trailers are played through various radio stations depending on the subject and audience of the trailer. Films such as those made by Disney could be heard on stations such as Capital FM for this will have the correct listening audience. All advertisements on radios are played through particular stations due to the audience. However, short films are displayed to a smaller audience and therefore are less likely to be advertised on the radio.

This link above is an example of a radio trailer. It is an advertisement for a 2013 horror film "The Conjuring".
As our film is also a horror theme, this is a good example to listen to for ideas for our own radio trailer advertising our short film "The Intruders".

Following the conventions of radio trailers, within our short film radio trailer we will include the conventions and construct them to suit our short film "The Intruders":

• using a voice over will enable our audience to hear information about the film, including the storyline and screening locations.
• sound effects will make it clear to the listener that our film is horror due to the eerie, sinister sound effects we will find and use. 
• because of these conventions we plan to use, the specific target audience will be easily aimed, as an 15 certificate rating.
