與DivX4相比,檔案大小可減少41%,壓縮效率則增加25%.
內建的壓縮工具,可裁剪,縮放畫面大小,
前置處理(Pre-processing),可濾除母帶中的雜訊,增加壓縮效率.
Psychovisual modeling技術,運用視覺系統原理來減低壓縮失真.
雙向參考影格(B-frames)壓縮.
全域動態補償(Global motion compensation)
以及許多可讓專家設定的進階選項...
詳細可參考以下解說:

* MPEG-4 Compatibility. DivX Pro is able to decode all levels of MPEG-4 Simple
Profile, MPEG-4 Advanced Simple Profile, and H.263 video. It is also capable
of encoding MPEG-4 Simple Profile and MPEG-4 Advanced Simple Profile video.
(ISO/IEC 14496-2).

* DivX(tm) MPEG-4 file format. DivX Pro includes support for the new DivX(tm) MPEG-4
file format (encoding and decoding).

* Smaller file sizes. The advanced techniques and tools of DivX Pro mean that
the same visual quality can be achieved at up to 41% smaller file sizes than
DivX 4.x. This represents up to an additional 25% improvement over DivX 5.0.

* Integrated video encoding tools. DivX Pro includes built-in video encoding
tools that are tightly integrated with the core codec. This include:
de-interlacing, resizing, cropping, and intelligent inverse telecine and
deinterlacing mode. This tools normally are included in separate applications
at additional cost.

* Pre-processing. DivX Pro includes patent-pending noise reduction
pre-processing algorithms that can dramatically improve the compression
performance on video sources that normally contain a lot of noise such as
older movies.

* Psychovisual modeling. DivX Pro includes psychovisual modeling, an advanced
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.

* Bi-directional encoding (B-frames). Full support for bi-directional encoding
(B-frames).

* Global motion compensation. Global motion compensation provides special
encoding tools to deal with common panning and zooming sequences within video
sources.

* Quarter pel. DivX Pro includes the capability to analyze block movements
from frame to frame to the quarter pel level.

* Data partitioning. DivX Pro includes support for data partitioning, where
the software organizes the video data differently in the video stream, making
the video stream more resilient to transmission errors when it is broadcast
over lossy networks.

* Advanced support for existing encoding applications. All the advanced new
features of DivX Pro are designed to work immediately with existing video
encoding applications and require no application updates in order to work.
