Stereoscopic imaging creates the illusion of depth by showing each eye two slightly different images. This is the technique in the making of 3D films, which are advertised using 3D movie trailers.
3D movie trailers usually consist of scenes from the film, but they are not necessarily shown in the same order as they are shown in the film. This is done to avoid giving spoilers. The scenes that are to be chosen are the funniest, the most interesting or the most emotional, anything that can catch the viewer’s attention. Originally, trailers were shown at the end of a film, thus the term, but this was later changed since moviegoers usually leave the cinema at the end. Trailers are now shown before a film starts.
The parts of a trailer for a regular feature film and a 3D film are basically the same. The following are some of the parts of 3D movie trailers.
The voice-over is a helpful tool in enhancing the viewer’s comprehension of the film. It gives the necessary comments that the scenes alone cannot provide.
Music helps in setting the mood of the trailer/ film. It is carefully chosen by the crew and filmmakers. The music can be from popular songs or from songs that are specially composed for the film. In the last part of the trailer where the most emotional scenes are shown, music plays a very important role.
Information on the cast, crew and studio
Towards the end of the trailer, a cast run is usually shown, but this is only done if the actors and actresses are well-known personalities. This is to boost up the advertising of the film, or to promote the actors and actresses. Through this, people would be more enticed to watch the film. The studio logo and other relevant information are usually shown at the start of the trailer.
Like the plot summary of a film itself, the plot summary of a movie trailer has a three-act-structure. The first lays out the premise of a story. The second starts with the rising action and ends with the climax. When the trailer comes to a close and the signature music come on, and the most emotional scenes are shown, that’s the last part. The last part can also include the cast run, if it can help further in the advertisement.
