Sorenson Media today announced an update to the Mac version of the Sorenson Video 3.1 Pro video codec. The new codec addresses a compatibility issue with Mac OS X 10.3 (Panther). “During Panther pre-release testing, the Sorenson Video 3 Pro codec was not listed within the Apple QuickTime codec options; however, the 3.3 update resolves this compatibility issue,” notes the company.  Sorenson Squeeze 3 Compression Suite and Sorenson Video 3.1 Macintosh customers are able to download the free Sorenson Video 3.3 Pro video codec update today from the Web site.
