the 'Next 5 Minutes' festival of new media is on in Amsterdam at present. Part of the event is the temporary creation of a huge online media library with high quality MPEG 4 files of activist/political film and video. The selection available is awesome and includes the brand new 'We Interrupt this Empire' documentary on the shutdown of San Francisco at the start of Gulf War II.
It also really gives you an idea of the vast amount of Activist Video being made and not being seen and to me points up a need for an ongoing library of this stuff being available online.
The quality of the files is fine for screenings and all you need to do so is access to a laptop and a video projector.
So if you have a fast connection (I don't) then get downloading.
