SO WHAT IS THE ACTUAL AIM OF TEASER TRAILERS?
A teaser trailer is a quick trailer used to promote an forthcoming film, television program, video game or similar, usually released well advance of the product, so it is there to "tease" the audience. To establish movie and location, answering questions such as: Where does this film takes place? What is setting? It immediately establishes the characters- we get a hint about who the significant character’s are and who are not; principles of the story who are they? We begin to decide why we like them? As it emphasises on funny/likeable characteristics etc. Towards the middle the first major plot device is ravelled the story begins to roll. There is this build up in action and intensity until rapidly paced clips collide into an ultimate knock out blow at this point (being only a teaser) it should allow the audience to decide whether they would do more research on it and possibly want to watch...the ending should leave the audiences saying a film they want to see.

CONVENTIONS OF A TEASER TRAILE
SIGNIFICANCE OF PRODUCTION/DISTRIBUTOIN COMPANY.
Firstly teaser trailers are inclined to start with the production/distribution companies logo which immediately signifies that what your about to see is going to be high/low budget or even sometimes preference of a particular production/distribution companies.

CERTIFICATION
There is always a certification alerts to indicate the target audience of the film.

STAR PERSONA
To publicise the film more teaser trailers may assert the names of cast and crewmembers, who will be commonly notorious and in turn draw in audiences products they have been in before or produced, directed etc. May use this opportunity to introduce and promote new talents.

VEIWS AND NOMINATIONS
A variety of other ways are used across film teaser trailers; this may include the use of nominations, awards and highly recommended reviews such as Oscars, Baftas etc. These methods assist in drawing in an audience, particularly if these reviews are from a reliable source indicating the production will almost certainly be of a high standard. However this may not be necessary in certain movies or film industries for example in Bollywood cinema the star persona is ALL important!

INTER-TEXTUAL REFERENCE.
Many teaser trailers include inter textual reference; these are slight inclusions of similar themes to a film, or text that the production has been influenced by for example

NARRATIVE MYSTERY
A semiotic tool which is used in teaser trailers is narrative mystery and I think it a crucial tool for promoting and selling the product that the teaser trailer is representing. As viewers of the trailer will want to have their questions answered; the only solution is to go and watch this movie.

THE NEED OF A RELEASE DATE
The release date usually appears at the end of the teaser trailer, after the effects and marketing methods have been used. The date is incredible integral as without this date the audience will be oblivious of when they will be able to view this production.

THE IMPORTANCE OF EFFECTIVE EDITING
Editing is one of the chief points that move around trailers, fast paced editing is incorporated with numerous different camera angles, to keep the viewers of the clip enticed; as one continuous shot through out wouldn’t give a sense of uncertainty that is associated with teaser trailers.

WHAT CLIPS TO USE AND WHY?
The clips that are chosen to be included into the teaser trailer are also one of the vital aspects in making a teaser trailer; clips need to be chosen that give away only certain amount of the narrative yet insuring not much of the plot if given away.

USE OF SOUND.
Audio is just as vital as visual in when it come to conventions that are found in teaser trailers. Non-diegetic music usually comes in before the clip this is to help affix the genre of the film.

USE OF VOICEOVERS.
Voiceovers are also used in trailers to dictate what is going on throughout. Stereotypically a deep male voice is used in action genre to create a higher sense of excitement however if a female voiceover was used it wouldn’t have the same affect as this trailer is advertising a action movie. Yet would suit a romantic comedy perfectly.
