Movieclips,com, a online movie clip service based in Venice, on Wednesday said that it raised $18.5 million in a Series C funding round and was renaming itself Zefr.

The round was led by U.S. Venture Partners of Menlo Park. Zefr, which launched in 2009, offers a proprietary technology to identify and catalog licensed content posted online. It has deals with six major Hollywood studios and YouTube to monetize premium content, including social networking features for film buffs.
