Computing News | DivX 6.2.0 Beta

DivX 6 is available through two new product bundles: the DivX 6 Play Bundle and the DivX 6 Create Bundle. The DivX 6 Play Bundle contains everything you need to playback all types of DivX video, including the new DivX Media Format. The DivX 6 Create Bundle contains the DivX codec and DivX Converter enabling easy creation of DivX media.
Changes in DivX Codec 6.2.0 Beta 1:
- Internal resize now supports threading. Performance gains of over 40% can be seen when using the Balanced (default) encoding mode on a Pentium D Extreme Edition CPU and resizing anamorphic D1 material to square pixel (1:1 PAR) equivalent verus the same configuration with threading disabled.
- A new "Enhanced multithreading" performance option is available that can increase encoding rate under circumstances where the input to the encoder is not immediately available. Examples include production suites that render effects during exporting, transcoding a source format with a slower decoder, or encoding in applications with few pipeline optimizations.
- Typical performance improvement when running on Dual Core systems is around 16%. However, using our Pentium D Extreme Edition system to transcode HuffYUV source in Better quality mode we have seen encoding rate increase by up to 35% (equating to more than 11 frames per second!).
- "Enhance texture" is a new Psychovisual Enhancement method that improves quality for keyframes and reduces the appearance of stray blocks under fast motion. As with other Psychovisual Enhancement methods, the perceptual quality can be higher, although the PSNR metric RD performance is typically lower.
- There is now an MMX version of the MPEG quantization algorithm that may improve encoding rate up to 22% for older processors.
DivX codec 6.2.0 Beta 1 must be installed on top of DivX 6.1.1. During the beta period full DivX Pro functionality is available.
