A trailer is a device that attaches to the hitch of a car, truck, or other powered vehicle and allows it to haul equipment such as tools, construction materials, or recreational vehicles. A trailer can be either an open flat-bed or a boxed-in vehicle with shelving units or specialty equipment built in. The term may also refer to the trailer used by a truck driver to store his log book and record his hours of service.

When creating a film trailer it is important to include shots that reflect the genre of the movie. This will help audiences work out what to expect from the movie and helps them decide whether they want to see it or not. For example, if a film is a horror movie then the trailer should contain shots of characters looking scared. If the trailer is for a comedy then the trailer should include shots of people laughing.

Another important aspect of a trailer is the music that is used. It is important to find music that fits the tone and feel of the film. The music in the trailer should not be too heavy or fast. It should also not be too quiet or too loud. The music should also be in a key that matches the emotions of the scenes in the film.

The trailer is often the first thing that an audience will see before they go to a movie. Creating an effective trailer can be a challenging task. A successful film trailer will capture the audience’s attention and make them want to see the full film. A trailer will usually be about two minutes long.

There are many companies that specialize in the creation of trailers for feature films. These companies may be based in Los Angeles or New York City. They will create a trailer from scratch or edit a short film from the film’s rushes or dailies. A film editor may have to deal with multiple takes of a scene and choose which one best fits the trailer.

Many modern trailers are mixed in Dolby Digital or other multichannel sound formats. This gives the viewer a better sense of the film’s soundtrack and allows them to hear the dialogue more clearly.

A trailer for a feature film is usually created by the production company and/or the distributor of the film. The trailer may be presented in a theater before the main feature or it may be shown on television before the film’s broadcast premiere.

The National Association of Theatre Owners has set a guideline for trailers asking that they be no longer than two minutes in length. This is in response to the growing number of films that are being released with shorter running times than the standard two hours. It is also designed to prevent audience members from leaving during a trailer and missing the start of the film. In addition, the National Association of Theatre Owners has asked that trailers be provided by film distributors in a standard format that is compatible with all movie theater systems.
