Wikimedia is partnering with the collaborative video service Kaltura to start rolling out video to Wikimedia sites. Right now, the feature is available on the WikiEducator demo site, which is not affiliated with Wikimedia. But eventually we'll start to see collaborative video hitting Wikipedia as well.

Kaltura videos can be created and edited by anyone, much like Wikipedia pages. You can also see previous versions of a video and a list of people who have worked on it. Users can also upload audio, slideshows, and other rich media. If you want to get your feet wet editing a video, check out the collaborative video sandbox.

Kaltura is making its code open source to support the goals of Wikimedia, and all audio and video will be encoded in the open source OGG Vorbis and OGG Theora formats.
