One of the really cool ‘web maker’ projects that Mozilla sponsored in the last few years was Popcorn Maker, an in-browser video editor that could take direct video clips or videos from Youtube etc and let you remix to your heart’s content.
Unfortunately Mozilla has to shuffle priorities, and Popcorn Maker is on the outs.
Fortunately, there’s enough interest in the Wikimedia video world that we’re helping to pick it up!
If you’re interested in helping out, we’re going to have some work sprints at WikiConference USA next weekend in Washington, DC. Please come and help out!
