Sound is one of the most important things that can determine whether a teaser trailer is good or not. This could be in terms of many ways, for instance whether it will help make the teaser trailer much more effective in terms of how scary it appears or whether it may help contribute to the trailer making the film seem good when in fact it is not.
There are many different types of sounds in which editors use in teaser trailers in order to make them convince the viewers to want to go and watch the film.
These are some of the different types of sounds:
Diegetic Sound: Sound heard by the characters in the text as well as the audience.
Non-Diegetic: Sound: Type of sound added to the text for the audience only.
Synchronous Sound: Type of sound that is times to match the movements occurring in the text.
Sound Effects: Artificially created or enhanced sound, used to emphasise content.
Dialogue: This is any speech made in the content.
The above sound is usually mixed and balanced in order to create the necessary emphases which in turn help to create the desired effects.
Below are some horror teaser trailers i took a look at and in particular paying attention to the sound in which they used.
Saw 3D Teaser Trailer
The production company logo appears along with a short and snappy sound effect to go with it. Unlike most of the teaser trailers we looked at, this one has a voiceover throughout the trailer. There is also some non diegetic sound to help maintain the effectiveness of the sound overall. Like many other teaser trailers, it does however have some sound effects to accompany the captions. Other sound effects that are used include a scream and machines being used. In this trailer, the music starts to build up and get faster at around 33 seconds. Compared to all these other teaser trailer, this one also ends with its non diegetic sound fading out.
Insidious Teaser Trailer
Just like the other three teaser trailers we notice that this teaser also has some non diegetic sound effect that starts to play when the production company logo appears on screen. Synchronizing sound is also used when the captions appear on screen. This teaser trailer also uses incidental music that builds tensions, especially when they are quick cuts playing. Diegetic sound is also used within the teaser and there are parts in which we notice the sound gets louder and softer in order to keep the viewers alert and anxious.
The Crazies Teaser trailer
In this teaser trailer we notice that there is no sound for the first 8 seconds of it.
When the production company logo appears, it is accompanied by some non-diegetic sound and a sound effect of what sounds like a soft drum/heart beat.
The next shots of the girl strapped on a bed uses some diegetic sound with non diegetic sound that is also in the background. This is a good effect as if does not make the teaser trailer sound dry at this point. It helps to maintain the flow of the sequence along with its music. This teaser trailer then also goes on to use more foley sound effects that synchronize the action on screen, for example the unlocking door sound, the spreading of fire sound and the scream of a girl. When captions come up we notice that there is a specific sound in which accompany them. This is good as it keeps the continuity going in the teaser trailer. Other hard sound effects we hear at the end include an explosion sound. Incidental music to build up the tension is used from about 26 seconds for some few seconds. We also notice that when there is a blanc screen for more than a second, the sound stops and then starts again.
In comparison we notice that all these teaser trailers use sound and music that anchors the footage. We also realise that every sound effect that each uses either goes with what is happening on screen or flows with the captions.
Comparing these three teaser trailers makes us realise that teaser trailers use sound in a very effective way as it helps to create tension. For instance when all the quick shots are playing the sound gets louder, more distinctive and fast paced in order to create that frightening feeling that makes you anxious to want to know more.
By looking at these teaser trailers as well as others. we have noted the sound in which we use in our teaser trailer is very important as it could make a big difference to how the audience like or see the trailer. It has also helped us realise that in order to make our teaser trailer flow we need to mix and balance out different sounds not just use one sound. These also helped us gather ideas of the sort of music and sound we should be looking at including in our teaser trailer.
