- What's new in this version
- --------------------------
-
- **Features of DivX Pro 5.0**
-
- * 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.
-
-
- Known Issues
- ------------
-
- * Psychovisual modeling may cause artifacting in some content. This
- issue will be addressed in the next release.
-
- * Protecting logs not functional. Be sure to rename your two pass logs
- to prevent them from being overwritten if you would like to reuse
- them.
-
- * Resizing may cause errors.
-
- * Save setting to a file is not functional. Settings can be saved for
- future reuse only locally to the registry. If you would like
- to share these settings easily, just use your "command line" string.
