What is the purpose of Teaser Trailers?

For my A2 level media project I have chosen the medium of producing a teaser trailer which will be accompanied by an original piece of music and possibly a voiceover. First of all, I have researched on why teaser trailers are assembled and how they are composed. The most vital reason is that they are used as a marketing devise to promote an upcoming film. Teaser trailers are usually very short in length, between 30 and 60 seconds. They contain little, if any, actual footage from the film to create awareness and hype for the film.


They are usually released long in advance of the film they advertise, to make people aware of its existence. Teaser trailers inherite their name from 'teasing' the audience to want to view more and recieve more information about the film. This is one of the main 'Unique Selling Points.' 
Teaser trailers and often be confused with theatrical trailers. The main differences between the two are theatrical trailers flesh out the plot of the film previewing some of the best parts to increase the audiences enthusiasm and entice them to see the film, without producing spoilers. They also exist for a longer length of time, usually 2- 3 minutes. Trailers have become highly polished pieces of advertising able to compliment even poor films in an attractive light. 

To develop a clear understanding of the involvment in teaser trailers, I am going to find out the codes and conventions of teaser trailers, to help and encourage me to develop my skills for my own teaser trailer product.
