Check out The Assistant Editor at http://www.theassistanteditor.com/. I found it via Flowseeker. From what I understand you can use this to assemble a rough cut of your documentary automatically. What you do is that you tag all your footage and audio as either a-roll or b-roll and by it's subject matter, characters in it, etc. Then you tell The Assistant Editor to assemble the footage into a doc that focuses on a certain theme. The program puts together the cut based off of the tags you give it.
There's a video on the site of how to create a rough cut of a doc with it here: http://www.theassistanteditor.com/howitworks.html and the results of that tutorial are here: http://www.theassistanteditor.com/results.html
