| 1. Introduction
+=========================-
DARC is proud to present the DivX 6 codec; the result of over
one years' development in improving quality, compression,
performance and design.
The DivX 6 codec achieves between 20 and 40 percent better
compression than its DivX 5 counterpart and creates the
highest quality video for our new DivX Media Format. The DivX
Media Format supports advanced features such as interactive
video menus, chapter points, multiple audio tracks, XSUB(tm)
subtitles, XTAG(tm) video information and more.

Have fun and enjoy this release,

| 2. New in this Version
+=========================-
* Support for the DivX Media Format
The DivX 6 codec includes full support for the DivX Media
Format and enables access of DivX Media Format features for
.divx files in all popular media players. Look for the DivX
icon near the clock on your taskbar to select special
features whenever you play a .divx file.
Through the DivX Media Format you can now experience
interactive video menus, chapter points, multiple audio
tracks, XSUB(tm) subtitles, XTAG(tm) video information and
more.
* Includes new DivX 6 decoder
The DivX 6 decoder features improved playback performance
and video quality. Experience stunning DivX High Defintion
video like you've never seen it before.
* The DivX encoder GUI has been redesigned
The encoder configuration interface has been redesigned for
ease of use. Related items are better grouped, there are
fewer wizard-style screens to navigate and the dialog window
itself is much smaller than before.
* Performance modes have been adjusted
Codec performance modes have been adjusted according to a
rate-distortion model and with respect to functional use
cases. This better balances video quality against the rate
of encoding.
* Two new performance modes have been added
Extreme quality mode has been introduced to improve video
quality at the expense of encoding time. Insane quality mode
has been created to enable all bells and whistles regardless
of encoding time.
* Rate-distortion optimized H.263 quantizations
Block search duration has been reduced for motion estimation
leading to higher encoding rates.
* New aspect-based resize
It is now possible to resize given the source aspect and
output width rather than absolute video dimensions.
* Support for 4MV
4MV is now supported, creating clear improvements in picture
sharpness and reducing ringing artifacts.
* Improved deblocking
A new proprietary deblocking algorithm improves visual
quality and PSNR while reducing decoder complexity.
* Multiple consecutive bidirectional coding
Multiple B-frames are now permitted in DivX High Definition
(HD) profile, enabling greater compression for HD video.
* VBV change for Portable profile
The VBV constraints for Portable profile have been adjusted
to take full advantage of real-world DivX Certified portable
devices. Video created using Portable profile with the
DivX 5 codec is fully compatible with the new VBV model.
