Divx 6: High-Resolution Video Saves Space

A Comparison Of Codecs: Divx Vs. WMV9 Vs. MPEG-2

The software used in testing the different codecs: Tmpg Encoder from Pegasys. Our test video is available in 16:9 format - the specification of 720x576 pixels (4:3) is incorrect.

A summary comparison of different video compression formats: at an extremely low data rate of 250 kBit/s, Divx 6 and 5.2.1 are unbeatable. The WMV9 codec exhibits obvious blurring. All DVD movies still use MPEG-2, a codec that is outdated and has big problems at lower data rates.
