This is the latest version of the codec DivX 5 ! The best and the most used codec in the world ! :You need to insatall this software if you want to encode a divx5 movie or if you want to see a MPEG 4 movie.
What’s New in This Release:
New:
· Added a new high-quality psychovisual mode that includes the following features:
· Texture cortex masking and rate distortion algorithm
· Hybrid mode (with texture cortex masking)
· Speed optimization
· Chroma 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 file
· An API that allows real-time control of rate control
· An 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.
