Carl Rosendahl, founder and former CEO of animation and f/x studio PDI (“Shrek”), has joined Internet video developer iVast as chairman of the Santa Clara -based company’s board of directors.

Rosendahl is expected to help attract more entertainment clients to the company’s MPEG-4 technology solutions and to iVast’s new Culver City MPEG-4 production, encoding and authoring studio. He also serves as managing director for Mobius Venture Capital and was previously a board member of iVast.

MPEG-4 is an audio and video technology that condenses large digital packages into small files that can be easily transmitted via the Internet to set-top boxes and to wireless devices, much like MP3 has done for music on the Web. In addition, MPEG-4 allows video to behave like a Web page and enables viewers to interact with content on the screen as it plays.

IVast has also pacted with James and John Cameron’s EarthShipTV to jointly develop and deploy interactive entertainment events for http://www.earthship.tv.

In 2001, Los Angeles-based EarthShipTV followed James Cameron’s return expedition to the Titanic, streaming live to the Internet from above and below the North Atlantic via satellite for four weeks. Later, the company hosted the Arthur C. Clark 2001 Gala live from the Playboy Mansion and projected Clark via satellite from Sri Lanka as a real-time, interactive 3D hologram. This year, EarthShipTV will follow Cameron on a deep-ocean expedition to the site of the sunken WWII battleship Bismarck.
