This document discusses the conventions of documentary films. It begins by defining what a documentary is, noting that they focus on real people and events to create a point of view for the audience. Documentaries use techniques like titles, charts, maps and reconstructions to present factual information. They typically only have one camera operator and sound person for mobility. There are three main types of documentaries: compilation films using existing images, interviews that record testimonies, and direct cinema that records events as they happen. Modern documentaries are less scripted and more observational. Common documentary conventions discussed include using archival footage, interviews with subjects, shaky camera work, voiceovers, and reenactments.
