- What's new in this version
- --------------------------
-
- **Features of DivX 5.0**
-
- * Compatibility with all versions of DivX video content. DivX 5.0 can play
- every version of DivX video ever created, from prior to 3.11 alpha to the
- brand new DivX Pro 5.0.
-
- * AMD optimizations. Version 5.0 is fully optimized for AMD Athlon and Athlon
- XP processors.
-
- * Faster two-pass encoding. The second pass of two-pass encoding is now up to
- 30% faster than DivX 4.12. The second pass makes use of motion vector
- information calculated by the first pass.
-
- * Smaller file sizes. DivX 5.0 is capable of producing equivalent visual
- quality at up to 15-20% smaller file sizes, when compared to DivX 4.12. File
- size savings will vary depending upon the nature of the video content.
-
- * MPEG-4 compatibility. DivX 5.0 can decode MPEG-4 Simple Profile, MPEG-4
- Advanced Simple Profile, and H.263 video (all levels). It is also able to
- encode fully MPEG-4 Simple Profile compliant video (ISO/IEC 14496-2).
-
- * DivX(tm) MPEG-4 file format. Full support (encoding and decoding) for the brand
- new MPEG-4 based file format that replaces the venerable AVI file format.
-
- * Advanced support for existing encoding applications. All the new features of
- DivX 5.0 work in today╒s existing content creation and encoding applications
- without requiring new versions of the applications.
-
- * Reusable encoding profiles. Version 5.0 allows you to save profiles of
- encoding settings and reuse them over and over. You can also trade encoding
- profiles with other users.
-
- * Quick configuration CLI. DivX 5.0 includes a command line interface for
- advanced users.
-
- * Patent-pending rate control algorithm. This new version of DivX introduces a
- new and improved rate control algorithm, improving visual quality.

- * Improved encoding algorithms. Includes special encoding algorithms that are
- specifically tuned to pans, fades, zooms, explosions, etc., improving quality
- and increasing compression.
-
- * Psychovisual modeling. Support for advanced psychovisual modeling during
- encoding, a technique that takes into account knowledge about how the Human
- Visual System (HVS) works to compress moving video images into much smaller
- sizes without a loss of video quality.
-
- * Universal architecture. The universal VfW/ACM/QT architecture of DivX makes
- it possible to playback exactly the same file on a variety of different
- operating systems and applications.
-
- * Scalable. Work on a wide range of video bitrates, from 28 Kbps to 9 Mbps,
- depending upon your encoding needs.
