Documentaries employ certain codes and conventions in editing, sound, graphics, cinematography, and other elements. Interviews are typically conducted with the interviewee in a close-up or medium close-up shot on the left or right third of the frame, facing the interviewer seated across from them. Graphics anchor the relevance of interviewees with their name and relevance in two lines. Archive material and chromakey footage are used to illustrate points made by narrators.
