The document discusses what the author learned about filmmaking technologies from creating a two-minute film opening. It describes using a Canon 550D camera that allowed HD filming and zooming to get close-up shots. Final Cut Pro was used to edit the film and add effects like flashbacks. Problems encountered included a lack of creative filming locations and technical issues with the camera stopping recording. The author proposes improvements like adding a knife to the serial killer to make them seem more threatening and filming in a real police interrogation room.
