Documentaries typically follow certain conventions regarding their structure, camerawork, voiceovers, and editing. Narratively, they tend to be single-stranded with themes throughout and a voiceover that ties the story together. Visually, establishing shots are used to set the context while interviews employ close-ups, rule of thirds framing, and creative camera angles. Sound-wise, voiceovers provide context and facts, music heightens emotion, and effects are included in reconstructions. Graphically, white text stands out for titles and credits while titles identify interviewees. Archive material must be relevant to the topic and voiceovers further explain context. Cuts, dissolves, and montages are common editing techniques.
