1. Trailers and teasers
What's the difference?

2. My research findings
I have looked at a total of 12 trailers and teasers and the
following slides will discuss the differences and similarities
that they posses referring to the following aspects:
Sound/music
Mise-En-Scene
Cinematography
Editing
Choice of Titles
Special Effects
Narrative
Genre

3. Sound/music
Trailers
Tend to have a number of different tracks due to the
length of the video. The score can also often change as
the trailer introduces the 'problem' to the storyline, which
often sees a change in the tone. More is given away
about the film so sometimes songs created specifically for
that film are used.
Teasers
Teasers often use just one track due to their short nature.
The track will often reflect the mood/ genre but try not to
give away too much by changing tone to often or being
specific to the film.

4. Voice over
Trailers
Voice over can be common in trailers as a voice (usually
male) talks of the films ratings by well known media
establishments such as newspapers. Voice overs are also
used to introduce dates and the storyline. Speech
between characters is also common with that helping to
introduce the storyline.
Teasers
Teasers are similar to trailers in that dialogue is
sometimes seen to introduce the storyline, but not as
much due to the fact they do not give away as much.
Voice overs can be used to talk of dates, however these
are often not specific and state months or seasons rather
than days.

5. Genre
Trailers
Genre conventions can be evidenced throughout many of
the trailers and are introduced through a variety of
aspects including music, sound, mise en scene and
editing.
Teasers
Teasers are very similar to trailers in this aspect, often
introducing genre through the same means.

6. Special effects
Trailers
Trailers from that of a blockbuster production often include
several special effects. Trailers often give away more of
the dramatic events from the film.
Teasers
Teasers are different in that they often limit the use of big
scenes using special effects as they do not yet want to
give away too much. This may also be because
sometimes the teaser is brought out before the film has
completed production and these scenes may not have
even been shot.

7. Mise en scene
Trailers
Trailers often include various props, costumes and work
with the lighting and all other things in the scene to
produce an image that speaks for itself about the film's
genre. Some props can give away key aspects to the film.
Teasers
Teasers may only give away a little but in the teasers that
I have analysed the mise en scene, particularly props play
a big role. These enable the audience to understand the
genre and what the film is about. Without them, effectively
there would be no teaser at all.

8. Choice of titles
Trailers
Full theatrical trailers often give the production companies
involved, the director, dates, actors and ratings as well as
titles related to the storyline. These titles give away more
about the storyline as the film is often already playing at
the cinema around the time that the trailer is released.
Teasers
Teasers, like trailers often credit the production
companies, directors and occasionally actors. They rarely
use titles to give away too much about the storyline whilst
cannot give ratings as the film has not yet been released
to critics. Titles concerning dates are not as specific, often
talking of months or seasons rather than days.
