Like Andrew Overholt, I’ve recently been looking at the best way to host the pile of videos I’ve accrued over the last few years from recording talks with my DV camera. At the moment, I’m working on the stuff from FOSDEM 09 earlier this month, but I’ve also got recordings from the 07 and 08 events, our Sun Campus Ambassador talks over the last year and a half and many departmental group seminars from the university.
Imagine you’ve recorded a talk by Richard Stallman (as I did). In a derivative work, someone could alter the message Richard tries to get across to actively promote proprietary software. This is why both I and the FSF choose to use the Creative Commons Attribution-No Derivative license, as can be seen on the recent Stephen Fry video. This ensures that proper credit is given for the work and that it can be freely watched and distributed, while preventing such heinous modifications. Of course, if you’d like to create a legitimate modification, such as providing translation services or transcoding the video to a different format (provided it’s a Free format), then something can be worked out. But a blanket attribution of derivative rights is too risky.
I also now have a ‘show’ on blip.tv and have posted links to these videos on TheoraSea, a site for the promotion of Ogg Theora videos.
If you plan on posting your own content, I suggest you look carefully at what rights you are passing on to unknown third parties, and make wise choices rather than going for the most popular.
