The document discusses the various media technologies used at different stages of creating a trailer about serial killers. In the research stage, websites about serial killers like Wikipedia, allserialkillers.com, and crimemagazine.com were used to understand their behaviors. Photoshop was used to design the poster and magazine cover, and fonts were found on myfonts.com. Imovie on Macs allowed editing of video clips for the trailer. Copyright-free music was found on SoundCloud and converted to mp3 using zamzar.com for use in the trailer, which was edited in GarageBand and iTunes.
