One of the major advances of QuickTime 3 is the new Sorenson Video codec which is included as a standard component of the installation.It produces the highest quality low-data rate QuickTime movies.
The Sorenson Video Codec produces excellent Web video suitable for playback on any Pentium or PowerMac. It also deliver outstanding quality CD-ROM video at a fraction of traditional data rates, which plays well on 100mhz+ systems*.
Compared with [[codec:cvid;Cinepak]], Sorenson Video generally achieves higher image quality at a fraction of the data rate. This allows for higher quality, and either faster viewing (on the WWW), or more movies on a CD-ROM (often four times as much material on a disc as [[codec:cvid;Cinepak]]).
