MP4 Codec,

3ivx MPEG-4 5.0.1.208 is an MPEG-4 Part 2 Advanced Simple Profile
implementation for Mac OS X, Windows Vista and Linux. New in
3ivx MPEG-4 5.0.1 is an internal re-architecting that effectively eliminates
deadlocks and race conditions that can occur under certain circumstances
while dramatically reducing memory requirements. The decoder's performance
has been enhanced and memory usage while decoding has been reduced by
up to 76%. Intel and PowerPC Assembly routines have been implemented
for YUV image output and psychovisual post-processing, which dramatically boosts
performance and subjective video quality. Due to improved frame allocation
strategies pathological B-frame sequences can now be decoded without stalling.
he encoder now supports MPEG-4v1 and MPEG-4v2 syntax, which further
broaden 3ivx?s already impressive MPEG-4 device interoperability. CPU Complexity
Controls allow significantly faster than real time encoding and VBR, CBR and
ABR modes assist with performance critical workflows. Video Archiving and
Offline Production benefit from Dual Pass modes which perform optimal bitrate allocation.

3ivx MPEG-4 encodes faster and with better quality in a smaller file size than
QuickTime?s built-in MPEG-4 encoder and still retains the ability to target
all QuickTime 6 and 7 users without the need to download a decoder plug-in.

MP4 Export functionality has been added to the 3ivx Media Exporter for QuickTime,
allowing users to easily export high quality 3ivx MP4 files from iMovie, Final Cut
Pro and other QuickTime Applications. The resulting MP4?s are directly compatible
with most MP4 Players, including Apple's iPhone and AppleTV.

QuickTime compatible Aspect Ratio Signaling has been implemented within all
components of the 3ivx MPEG-4 DirectShow Filter Suite, allowing Windows a
pplication developers to produce and handle Anamorphic content which is
compatible with all Windows DirectShow players as well as Apple?s QuickTime
and AppleTV.

3ivx MPEG-4 5.0.1 builds on the solid base provided by 3ivx MPEG-4 5.0, which i
ncludes support for B-Frame Encoding, Interlaced Decoding, Global Motion
Compensation and Quarter Pixel Interpolation.

With this release 3ivx MPEG-4 5.0.1 Personal Editions are now available with
optional Multi-channel LC-AAC and HE-AAC audio support.

3ivx MPEG-4 5.0.1 is compatible with iTunes, iPod, Windows Media Centre
and most DirectShow, Video For Windows or QuickTime applications.
