What is an outline?

Quotes from research:

Outlines:

An outline is a sketch of your film, written to expose its proposed and necessary elements. In most cases, the outline is a working document for you and your team.

It would include a synopsis (one or two paragraphs) of the overall film story, and then a program outline broken down by acts (if applicable) and then a program outline broken down by acts (if applicable) and sequences, with detailed information on elements such as archival footage or specialized photography and interviews. (Curran Bernard 2004, p.115) The outline is a chance to begin imagining your film.  (Curran Bernard 2004, p.116)

Be careful to focus it as you intend (for now) to focus the final film. (Curran Bernard 2004, p.116) || What is the film about? Who’s story are you telling 

If the film is about events in the past or events you have control over (a series of demonstrations set up for the purpose of an essay for example), it’s easier to begin outlining the film and finding an appropriate structure. For films of events that will unfold as you shoot, it’s possible to draft an outline (and treatment) based on what you anticipate happening. (Curran Bernard 2004, p.116)
