Trailer definition and terminology

A trailer is a series of selected shots from the film in order to achieve its aim of advertising the film and attracting an audience/the viewer. Trailers tend to include the most exciting, funny or noteworthy parts of the film in order to stand a better chance of attracting the audience as they will think it looks good. They do not include any major parts of the film (spoilers) as this may ruin it for the viewer. The shots are not in the order that they appear in the film and the total time for the trailer has to be less than two and a half minutes. (2:30)


Terminology

Plot summary:
Film trailers have a plot summary that usually have a three-act structure similar to that of a feature length-film. The first act starts it off and basically introduces and lays out the premise of the story. This is then followed by act two which extends the story usually ending with a dramatic climax. And finally, act three consists of a visual montage of various clips (usually powerful and emotional moments) with a strong piece of "signature music" playing over the top. A cast run of noteworthy stars may also be used in order to help sell the movie.

Voice-over:
Voice-over is a narration technique commonly used in trailers in order to build up the story and provide explanation of important information to the viewer when necessary. It is primarily used to make sure that the audience have a clear understanding of the movies plot.

Music:
Music is used in trailers in order to add effect and set the mood. The music used is not usually from the film itself as it may not have been composed yet. It can be music from the score of other movies, popular music, music specifically composed for advertising, or songs such as knock-offs of recognizable ones.

Cast, crew and studio information:
The list of stars that appear in a movie is known as a cast run. Some successful and well known directors or produces will want a mention and to feature in the cast run. A billing block is used in the majority of trailers which shows a list of the principal cast and crew who worked on the movie. This can appear either at the start or end of the movie and tends to be the same list seen on posters or print publicity materials of the film. The logos of the production company and distributor of the film will also feature at the start or end of it.

Technical elements:
Sound mix - The majority of movie trailers are presented in multichannel sound mix such as Dolby Digital. They include sound effects and music that are enhanced by stereophonic sound in order to make them more effective and the main focus point.
Video resolution - Feature film movie trailers are usually presented in the same format as the feature - 35mm film or a digital format. Trailers can be distributed at any resolution up to 1080p with the help of high bandwidth internet connections.
