The 90 Second Film Challenge

Ben Green prefaced this project with a quote from “Mission Impossible”, but Bristol Wireless and Fluffy Logic have succeeded in the Challenge, making a succinct and informative promotional ‘infotisement’ on a minimal budget and lots of hard work. We’re really pleased with the result.

The movie is a speedy tour of our network, with interviews along the way. Entirely Free (Libre) Open Source software in its creation. The main video editing was done with cinelerra from

    Can it be a bit more clear that the bittorrent file is much much better quality. I was really hoping that we could distribute on bittorrent, but there hasn’t been one more download on the torrent since this page went up, probably as everyone is getting the small bad quality file.

    More to be torrents added soon.

    Just noticed another thing, that the the torrent file contains a license, which does not appear anywhere on this site. It’s bad if we distribute a file with no license attached, and doesn’t help people understand creative commons. A link to the license should be added, or the link to the mp4 file removed. It’s is not legal to pass this film on without a link to the license (at the very least).

    Until that happens, the license document from the torrent is as below:


    This film was completed using open source software.
    No proprietary software was used. The work was by
    Ell Southern, Ben Green and the rest of Bristol
    Wireless. It was the first time any of us had used
    Cinelerra. It was captured, edited and exported on
    Debian GNU/Linux.

    A brief episode with the superb Windows program
    VirtualDub created this compressed copy. The Unix
    program Transcode was needed to clean up the sound.
    We would have used transcode entirely, but it was
    crashing for DV input that day.

    The quality of this compressed piece also owes a
    lot to Donald Graft’s de-interlacing filter
    ( and those who helped create it.
    Without it there would have been blend
    de-interlacing, which would make it cloudy. Now
    it’s clear as a bell.

    The work is to be Attributed to:
    Bristol Wireless Community Co-operative Ltd.

    Hey guys, why no deriv’s? Could we also license it under /by/ or /by-sa/, or even /by-nc-sa/?

    For a good introduction to open source licensing

    Why no Derivs? No reason really. Since we are an organisation that can be easily contacted, I went with a license that everyone who was present could agree on. We could change it now, but can’t really add NC, as we have already released it for commercial use. I would quite like to use the Share Alike, but want for feedback on this.
