Two online movie-clips sites are suddenly angling for big attention at South by Southwest. Movie Clips.com, the Rich Raddon-Zach James site which appeared last December, has unveiled a new player. And this afternoon I’m dropping by the offices of AnyClip.com, which is will be promoting its presence in various ways at SXSW and launching on 3.15.

I don’t know anything. I’m just getting my feet wet. But the key to easy clip access is having a vast library (obviously) and providing embed codes — simple. Movie Clips.com has more money, obviously, but other differences require study.
