Research and planning: Why my trailer is a teaser trailer

My trailer has the conventions of a teaser trailer because:

• It is 1.20 seconds long therefore it is not long enough to be a theatrical trailer.
• Because only snippets of the film are shown this teases the audience and makes them want to watch the whole film.
• We took key scenes from our film which illustrated pivotal points such as love, conflict and tragedy. 
• We reorganised the scenes so they are not chronological so that we wouldn't give to much of the plot away, however our scenes would work to appeal to our target audience.
