DivX is a package that includes all the DivX codec, player, utilities, and documentation that you need to play DivX files. DivX codec is based on the MPEG-4 compression standard. This codec can reduce an MPEG-2 video (DVD format) to ten percent of its original size. DivX is a digital video compression technology based on the ISO MPEG-4 standard. DivX Networks claims that it includes speed improvements between 50 and 100%. 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 on your desktop 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 re-architected and is now 50 to 100% faster. 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. Added a high-quality B-frame mode. The motion estimation for B-frames is improved, and the quantization modulation is changed. 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. AVI importer's IMA ADPCM parser modified for more compatibility. 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 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 motion vector (MV) reuse to be non-functional. A bug that caused problems when MV reuse and psychovisual mode were used together. QuickTime 5 encoding and decoding support. Fixed bug with iMovie when importing media files with IMA-ADPCM or MP3.
