The most advanced version of DivX software available, designed for higher-end users.New:Added a new high-quality psychovisual mode that includes the following features:Texture cortex masking and rate distortion algorithmHybrid mode (with texture cortex masking)Speed optimizationChroma operation (this option is not enabled by default for performance reasons; to enable it, create an empty file in C: called "DivxPvShapingChroma.txt" for "fast" mode and "DivxPvSimpleChroma.txt" for slow mode; testing shows only 1-2% gains in JND tests)The decoder has been rearchitected and is now 10 to 30% faster on all CPU platforms.The decoder now supports automatic post-processing during video playback.Added new features to the rate control modes of the encoder, including:A complexity vector log fileAn API that allows real-time control of rate controlAn API that allows forced I-frame insertion Improved:Redesigned encoder GUI. The new GUI is more accessible and simplifies overall usage.DivX 3 compatibility. (There were no problems detected on any of the more than 60 hours of test content.)Performance of Nth Pass strategy planning performance.Fixed:A bug that caused the quantizer to overshoot the bitrate following a transition to a complex scene.A bug that limited the interframe change in quantizer to the ideal quantizer or plus or minus 2.A bug in RGB32 to YUV conversion on Pentium 4 machines.A minor bug that affected multiple CPU configuration.A bug with the rate control video buffer verifier (VBV) that would enforce a "3 sec" max bitrate. Several bugs that affected Nth Pass encoding strategy planning.A bug that caused a different number of frames to be reported between different passes in VirtualDub.A bug that caused motion vector (MV) reuse to be non-functional.A bug that caused problems when MV reuse and psychovisual mode were used together.Several bugs with the installer.A bug that caused a crash when setting crop/resize values.
