A treatment should be short, about two pages for a feature documentary. This is not a script. A treatment is a summary of how the subject will be approached, and it should generally elaborate on the concept. The treatment gives a feeling of where the story will go, beginning, middle and end. Important in the treatment are the issues that will be explored and what questions will be asked. The treatment should give the reader a sense of who, what, when, why, where and how. Written well it can help build interest in the documentary. (Martin 2018, p. 133)
A treatment that gives a strong notion of the envisioned documentary could be presented in a number of mediums including film or video trailer, photographic, portfolio, audio program or slide presentation. A well thought out concept and treatment provides a place to begin and it brings the idea to life.
