What Is A Trailer Mash?
  • In a trailer mash we take one or more films, and turn them into a trailer that is unlike the original films.
  • In this unit, you will be asked to:
    • Choose two or more films.
      • If the films are on DVD, you will need to rip them into digital files.
      • If the films are on YouTube, you will need to download them (try
    • Cut the films up to take out the pieces you want.
    • Edit the film pieces into a trailer for a different, imaginary film.
    • Make the genre of your trailer different from the genre of the original films (this is the fun bit).
      • E.g. you might take some horror films, and produce a trailer for a comedy film.
  • As examples, check out the trailer mashes below. The first is made from many films, and is for an imaginary sequel to Titanic. Instead of being a romantic comedy, it is an action film. The second changes a comedy, The Santa Clause into a thriller, using clips from only the one film:

Choosing Film
Hands On
  • Now you have seen some examples, choose one or more films to make your trailer mash from.
  • Apply to following guidelines when choosing:
    • Use films you own (e.g. on DVD or a legal digital download: no illegal torrenting, please) or that can be obtained from YouTube.
    • Choose films you know well (this will make it easier to find parts to use).
    • Choose films with enough flexibility to be able to change genres.
DVD Ripping
  • DVDs are designed to be impossible to rip (e.g. turn into a digital file).
  • In America it is illegal to rip a DVD (under a law called the DMCA), but in Hong Kong it is legal for personal reasons.
  • Under no circumstances should you rip a DVD and then share it, online or in person. This is illegal.
  • To rip a DVD, we can use some free, open source software called HandBrake.
    • Handbrake is also useful for converting videos from one format to another.
    • You might not have a DVD drive in your laptop, or it might not work for ripping: ask Mr. Parker if you need help.

Make Your Mash
Hands On
  • Use this time to produce your mash using video editing software such as iMovie.
  • Work slowly, and remember that it takes time and effort to get a good result when working with video.
  • The following steps might help you in making your mash:
    • Import your movie into your editing software
    • Use the Split tool to cut the movie into sections, deleting the parts you do not want.
    • Arrange the parts you do want into the order you want.
    • Use the Detach Audio tool to remove unwanted audio.
    • Record any extra audio you need (e.g. a voice over narrating the trailer)
    • Add in any sound effects (can you make your own? This can be really fun and creative)
    • Add in any music you want (remember, you can adjust the volume level to vary at different times)
    • Use audio and video transitions to make the video less abrupt and more polish.
    • Use intro and outro (e.g. credit) screens with text to add professionalism
    • Avoid using default/standard styles/fonts/themes to make your work more individual.
  • Keep showing your work to your teacher, friends and family to get their input. Apply their ideas to make your work better.
  • Make sure you have closing trailer-style credits at the end of your work, with your names as authors, and then names of the movies you used in your mash.
80 mins
Export, Share & Submit
  • Once your trailer is ready, export it and upload it to Google Drive.
  • Create a Google Doc, make sure to include:
    • A brief definition of trailer mash
    • The names and genres of your original films, and the name and genre of your new film.
    • Screenshots of your iMovie interface, to show how you edited the work.
    • A link to your trailer in Google Drive
    • A brief explanation of copyright and fair use, explaining why you were able to use copyrighted materials in your trailer (e.g. fair use of limited amounts of material for artistic, personal, non-commercial and educational use).
