XviD is an ISO MPEG-4 compliant video codec. It's no product, it's an open source project which is developed and maintained by lots of people from all over the world. Whats new :

• Large filesizes now work correctly in 2pass.
• Fixed possible out-of-bound-reads in 2pass.
• Bframe decoding fix - sometimes bframes were referencing wrong future macroblocks.
• Checking "use keyframe" in a zone now only makes the zone starting frame a keyframe.
• Internal pixel aspect ratio fixes - added display aspect ratio (for anamorphic encoding). Currently you'll need mplayer, vlcplayer (or 3ivx/Nero DShow filters) for correct playback.
• Colour space fixes.
• Directshow updates: brightness slider, postprocessing, output colour space choosable.
• Some more sse2 optimization for P4s.
• 2pass ratecontrol overhauled, including fast first pass.
• User selectable turbo mode. *silent update: 17:15h MET, 26.12.2003: updated dshow decoder*
