YouTube is adding Creative Commons–licensed videos to its editing library, and users themselves can tag their own videos with a CC Attribution License, thus enabling easy and newly legal remixing and repurposing of video content. Sharing is caring! Unlike Flickr, though, YouTube only lets you choose one kind of CC license: the kind that allows for commercial reuse. The library launched with 10,000 licensed videos — including ones from C-Span, Public.Resource.Org, and Al Jazzera — just in case anyone on YouTube was waiting for the legal go-ahead to remix newsy content.
