Richard Hering, from http://visionon.tv/ introduced this technique for making and uploading short videos in our English for Activists class in Tokyo.
They call it "Video Citizen Journalism," but, since not all of us are citizens of the countries in which we find ourselves, I prefer grassroots journalism or just smartphone journalism.
In any case, they have a handy leaflet that explains the most simple method, the One Shot News Report: http://streetreporter.org/en/tools
Seems like an approach that can be applied widely -- I plan to use it in my English language courses.
