DivX Pro Plasma codec has been focused strictly around improving video quality and compression. In our testing Plasma improves compression over DivX Pro 5.2.1 by 8 - 34% depending on bitrate and resolution, ultimately translating to better video quality without increased file size. Better still, all enhancements are within the confines of DivX Certified profiles so you can reap the benefits on your DivX CE devices with no impact on content compatibility. Changes: CoreBurn includes numerous fixes to the encoder GUI and functionality. Also bundled with this release is a newer version of the DivX DirectShow decoder, which includes performance and quality enhancements. Get it here.
