Agencies that specialize in creating trailers are known as trailer houses. Depending on the amount of influence the filmmakers have with the studio, they may or may not be involved in the creation of the trailer for their film. Some choose to closely supervise the process, when possible. They usually don't get involved until a version of the trailer has been approved by the studio internally. The producers and editors of a trailer will be given material from the studio to work with, which may include the movie itself (if it has been edited together yet), rushes, and/or computer graphics shots (as they are created during the film editing process). The trailers that are seen in theaters have been through an extensive process of revisions and approvals by a variety of studio marketing executives. The revision process often includes information from market research conducted at locations all around the country. Movie trailer editing benefits greatly from the use of a non-linear editing system. Most of prominent trailer cutting companies, Aspect Ratio, Trailer Park, New Wave Media and Buzz Image Group, have their editors work on Apple's Final Cut Pro or Avid Media Composer. Beside creative and unique trailer creation, there are several experimental approaches to generate movie trailers automatically using artificial intelligence. University projects like SVP (University of Bremen, Germany) analyse the movie and try to create--- a trailer based on typical structures and rules of trailers. Trailers that want to have an MPAA rating must submit the trailer for their comments and official rating. This process may take days to weeks. In addition, the trailer must go through TASA certification to regulate sound volumes across theaters. 【完】
