Sorenson, the software company that developed the compression technology included in QuickTime, has released a version 2.2 of its industry-standard video-compression codec.

Apple released Public Preview 2 of QuickTime 5 last week. The Sorenson Video codec is QuickTime-compatible and has been designed for applications and Web sites that need to use compressed video.

Version 2.2 offers improved performance and tighter compression rates. Registered users of Sorenson Video Developer 1.0 can upgrade to version 2.2 for $99. Users of more recent versions of Sorenson Video Developer are entitled to a free upgrade.
