In the grand tradition of actually getting things done on Wikipedia, Wikipedian KSheka, with some assistance from myself to convert the video to Theora, has gone ahead and uploaded a video of an "echocardiograph demonstrating systolic anterior motion of the anterior leaflet of the mitral value", which, translated, I think means "a video of a beating heart with a valve that's moving wrongly"
You can see the article with the uploaded video at
http://en.wikipedia.org/wiki/Hypertrophic_cardiomyopathy
Now we actually *have* a video in a patent-unencumbered codec uploaded to Wikipedia, and the ability to make more of them (transcoding to Theora is pretty straightforward once you've got ffmpeg2theora installed), the discussion about video I posted at http://meta.wikimedia.org/Video_policy becomes a little more directly relevant...
From my point of view, I'd be very interested in people's thoughts on
what we should do to make best use of video (one thing that comes to mind is that we should always take a still from the video as illustration, but more thoughts are good)...
Oh, and has there been any progress on implementing code for an approval process?
