Film Trailer Terminology

Definiton

Trailers consist of a series of selected shots from the film being advertised. Since the purpose of the trailer is to attract an audience to the film, these excerpts are usually drawn from the most exciting, funny, or otherwise noteworthy parts of the film but in abbreviated form and usually without producing spoilers. For this purpose the scenes are not necessarily in the order in which they appear in the film. A trailer has to achieve that in less than two and a half minutes, the maximum length allowed by theaters. Each studio or distributor is allowed to exceed this time limit once a year, if they feel it is necessary for a particular film.

Some trailers use "special shoot" footage, One of the most famous "special shoot" trailers is that used for the 1960s thriller Psycho, which featured director Alfred Hitchcock giving viewers a guided tour of the Bates Motel, eventually arriving at the infamous shower. At this point, the soft-spoken Hitchcock suddenly throws the shower curtain back to reveal Vera Miles with a blood-curdling scream.

The people who create trailers often begin their work while the movie is still being shot. Since the edited movie does not exist at this point, the trailer editors work from rushes or dailies. The trailer may be created at agencies such as;

• The Cimarron Group
• MOJO
• The Ant Farm
• Aspect Ratio
• Trailer Park

while the movie itself is being cut together at the studio.

Terminology

• Plot summary
  Most trailers have a three-act structure similar to a feature-length film. They start with a beginning (act 1) that lays out the premise of the story. The middle (act 2) drives the story further and usually ends with a dramatic climax. Act 3 usually features a strong piece of "signature music" (either a recognizable song or a powerful, sweeping orchestral piece). This last act often consists of a visual montage of powerful and emotional moments of the film and may also contain a cast run if there are noteworthy stars that could help sell the movie.
• Voice-over
  Voice-over narration is used to briefly set up the premise of the movie and provide explanation when necessary ("In a world..."). Since the trailer is a highly condensed format, voice-over is a useful tool to enhance the audience's understanding of the plot.
  
  
• Music

         Music helps set the tone and mood of the trailer. Usually the music used in the trailer is not  from the film itself (the film score may not have been composed yet). The music used in the trailer may be:

• Music from the score of other movies
• Popular or well known music, often chosen for its tone, appropriateness of a lyric or lack-there-of, or recognisability.
• "Library" music previously composed specifically to be used in advertising by an independent composer.
• Specially composed music.
• Songs, which may include knock-offs of recognizable (but expensive to license) songs.

• Cast, crew, and studio information
• A cast run is a list of the stars that appear in the movie. If the director or producer is well-known or has made other popular movies, they often warrant a mention as well. Most trailers conclude with a BILLING BLOCK, which is a list of the principal cast and crew. It is the same list that appears on posters and print publicity materials, and also usually appears on-screen at the beginning (or end) of the movie.
• Studio production logos are usually featured near the beginning of the trailer. Until the late 1970s, they were put only at the end of the trailer. Often there will be logos for both the Production Company and distributor of the film.

  Technical elements

  • Sound mix: many movie trailers are presented in Dolby Digital or any other multichannel sound mix. Scenes including sound effects and music that are enhanced by stereophonic sound are therefore the focus point of many modern trailers.
  • Video resolution: movie trailers preceding feature films are generally presented in the same format as the feature, being in general terms 35mm film or a digital format. High bandwidth internet connections allow for trailers to be distributed at any resolution up to 1080p.
