Teaser trailers.

Okay, so, I've looked at some teaser and theatrical trailers. This has helped me come to some conclusions;
- Most teaser trailers are between 30 seconds to a minute long.
- The name 'teaser' trailer can be very literal, ie, some may not even include that much footage from the actual film. The idea is to tease the audience. Another reason for this may be that the teaser trailer is released a long time before the full length film, so the editing and production may not be properly finished yet. This all is intended to just add to the hype, merely to let the audience know that the film is coming - rather than explaining the plot itself.

Because I've picked to try make a Thriller trailer, I need to follow certain conventions, like;
- Most Thriller type trailers include sped up footage.
- Usually there are lots of fast cuts/transitions.
- Shots or transitions that might make the audience jump - Most Thriller fans like the adrenaline rush.
- Surrealism.
- Sometimes CGI footage.
- Little indication of the direction of the plotline.
