Documentaries follow certain codes and conventions according to John Corner. They typically include observation footage showing an event as if the audience was present, interviews to provide different perspectives, and dramatization to further immerse the audience. During production, elements like music, interview techniques, and selective editing shape the overall message. Like other media, documentaries also have a beginning to introduce the topic, a middle to present evidence and conflict, and an end to resolve any doubts and leave the audience with a new perspective. However, they are not considered news programs and aim to explore issues in more depth through human experiences rather than opinions.
