| 1. Introduction
+=========================-
Welcome to the DivX Pro Fusion codec!
Following more than a year of research, development and architectural changes,
DARC are proud to present this beta version for testing. Amid a sea of new
features and enhancements, a new GUI, better video quality and better encoding
performance are just a few of the highlights on offer.
For further information regarding this release please visit:

Have fun and enjoy this beta release,
- The DivX Team
| 2. New in this version
+=========================-
* 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 far 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.
| 3. Known issues
+=========================-
* This build has been tested on Windows 2K and XP operating systems only
* Automated update checking is disabled in this build
* Rotation of product artwork is disabled in this build
* It may not be possible to enter a bitrate over 4mbps under "unconstrained"
profile
* The Fusion installer will not remove old DivX codec Start menu shortcuts
* The "Display settings" button in the encoder feedback window may not function
and thus the additional setting controls may be unavailable
* The DivX Decoder may fail when the display adapter is configured for 16-bit
color (64K colors) or less.
