- Only made for big budget companies and popularly themed movies as independant film companies lack in budgets. Therefore cannot produce trailers of high quality.
- It is a shortened version of a theatrical trailer which lasts between 30 and 60 seconds.
- To 'tease' the audience to want to view the film, teaser trailers often contain as little information on the content of the film to project an upcoming movie
- Teaser trailers also commonly activates with fast cuts. For example, rapid montage editing, or begins with a slow pace, gradually accelerating. A vital code and convention is that they are released a long time prior to the films exhibition (mainly a year or a year and a half)
- They also present the most intriguing parts of the film, without spoiling the plot for the audience, as teaer trailers have limited time to grab their audience. They are also not previwed in chronological order
- Lighting, sound, shots and the overall atmosphere depend upon a particular genre. For example, horror films stereotypically would contain dark low key lighting and shadows accompanied with mysterious music to create an intense atmosphere. Where as, a comedy would bright and include happy, cheerful music to entice their audience.
- The films title is usually not viewed until the end, after the trailer has built to a climax where it then ends.
- Sound is very important in a trailer, particularly the music which accompanies the action, which can conduct our emotions and construct a specific atmosphere. The voiceover, a feature of advertising, is used to summarise aspects of the story and emphasize credit information where appropriate. Like every other element of the trailer, the voiceover also promotes the film by building our anticipation.
- The star personas often help advertise a film due to fans of the star and also helps understand the genre of the film.
For my teaser trailer I plan to follow the majority of these conventions as I believe these are the worthwhile ingredients to help engaging audiences and encouraging to sell a product in this particular area. I believe this is because most trailers would not follow these rules if they were unsuccessful.
