TrueMotion S According to the company itself, development started in the early 1990s. The first versions of the codec were mainly targeted at and used for
full motion video scenes in computer games. One of the codec's competitive advantages in this field was that, unlike
MPEG, it does not require a separate decoder, thus reducing costs to game publishers. This was the first version in the TrueMotion series of
proprietary lossy video compression formats and
video codec. This format compressed frame in either a 32-bit or 16-bit RGB
color space with a
FourCC of DUCK (or TMOT for a version of TrueMotion S that was licensed by Horizon Technologies). It is usually put in an
AVI container. The
filename extension varies from game to game. Some leave it with .avi, other games use .bin or .duc. Gaming consoles which were licensed to use the codec include the
Sega Saturn,
Simon & Schuster first person games such as
Star Trek: Borg also used the compression format. Some of the files can be played back with a video player that uses the
libavcodec library, such as
MPlayer. In 1995, Horizons Technology Inc. began shipping the TrueMotion-S Compressor software for Macintosh and MS Windows. TrueMotion-S was originally developed by the Duck Corp. for applications such as the Sega game box. In 1996, the main competitors for TrueMotion S software codec were
Cinepak and
Indeo in games for first-generation CD-ROM based game consoles.
TrueMotion RT The "real time" version in the series was released in 1996. It was meant for real time capturing and processing of digital video.
TrueMotion 2 The second version in this series only supported a 24-bit RGB
color space optimized for Windows rendering which orders components as BGR with a
FourCC of
TM20. Used for
Final Fantasy VII and
Star Trek: Klingon. In 1997, Microsoft Corp. licensed The Duck Corp.'s TrueMotion 2.0 video codec technology to bring TV-quality video to the PC platform.
DK ADPCM Audio 3/4 There are two obsolete versions for associated
ADPCM audio compression.
TrueMotion VP3/4 On June 1, 2000, brought version 3.1; August 16, 2000 version 3.2. The third version in the series switched to using a planar Y'CbCr 4:2:0
color space. In late 2001, On2 released their
VP3(.2) compression technology into the open-source community including their patents on the technology. The technology lives on in the form of
Theora. The
Xiph.Org Foundation created its codec
Theora as a fork of the codebase of VP3.2. The forked version added 4:2:2 and 4:4:4 sub sampling for better color quality options. In April 2001 VP4 was published, which brought an improved encoder for the same bitstream format.
TrueMotion VP5/6 A preview version of VP5 was published on February 21, 2002, with production version being available as of May 1, 2002. The production version of VP5 codec was released in May 2002. When the codec was in
beta, to preview its quality, On2 created a plug-in for
RealPlayer. More recently, On2 licensed its technology to AOL for use in an IP-based video telephony product, to Tencent Holdings of China for use in its instant messaging products, and to Saver Corporation of Japan to enable new Flash 8 mobile video applications. On May 12, 2003, On2 announced the release of VP6. Revised versions 6.1 and 6.2 followed later that year. Since October 2003 it may be used free of charge for personal use. In late 2003, On2 announced that its VP5 and VP6 codecs were selected by Beijing E-World as a video coding method to be used in a Chinese-developed competitor to the
DVD format called the
EVD (Enhanced Versatile Disc) format. Then in April 2004, On2 announced that its business relationship with E-World had soured, and that On2 would file multiple breach of contract claims against E-World in arbitration proceedings. The arbitrator reached a conclusion on March 10, 2005, according to
SEC filings by On2 on March 14, 2005. The arbitrator dismissed each of On2's claims and ruled that E-World owed nothing to On2 and had not breached the contract. It seems unlikely that On2 will ultimately get any significant payback from the EVD initiative, although some contract relationship remains in effect. A number of less highly visible deals with other customers and partners seem to have worked out more amicably than the Chinese DVD project. Recent announcements have related to deals with Apex Datacom, IWAPI Inc.,
Vividas, Digital Witness,
XM Satellite Radio, PowerLinx, and
LeapFrog Enterprises. In particular, the company indicated that it expected to recognize some revenue from the Leapfrog deal in the third quarter of 2005 and also made optimistic statements about the future with XM Satellite Radio. In 2004, On2's
VP6 was selected for use as the
Macromedia Flash Video 8 codec. This apparently stems from a deal made in the second quarter of 2004 with revenue in that quarter of $1.4 million for the licensing agreement. In related news, On2 announced on April 5, 2005, that it had acquired the Flix Flash video encoder technology from Wildform, Inc. On2 added support for Flash 8 video output to the Flix 8 product line that they released on September 13, 2005.
TrueMotion VP7 The seventh version changed the bitstream from previous versions for better coding efficiency and was released in March 2005; since July it may be used free of charge for personal use. It is a codec with both
VFW and
DirectShow support that On2 Technologies claims has better compression than leading competitive codecs such as
MPEG-4 AVC (H.264) and
VC-1. On2 Technologies announced TrueMotion VP7 in January 2005. The public release of VP7 codec software was available in March 2005. On March 9, 2005, On2 announced a new codec, VP7. On2 claimed that VP7 is superior to the
H.264/AVC standard, based on claims of comparative technical capabilities and licensing costs. This claim has been disputed by a developer of
x264, a popular H.264 encoder. In April 2005, On2 Technologies licensed On2 Video Codecs (including VP6 and VP7) for
Macromedia Flash. On December 1, 2005,
Skype announced that they had licensed current and future versions of its video compression software and had integrated it into the beta version of Skype 2.0 for point-to-point video conferencing
Skype protocol. No financial terms were disclosed relating to the deal. On August 13, 2007, On2 announced the addition of H.264 support to its
On2 Flix product line. Move Networks also used the VP7 codec in its Move Media Player plugin for Firefox and Internet Explorer, used by
ABC and
Fox for its streaming of full network shows.
TrueMotion VP8 VP8 was published in 2008 and marked the transfer of formats to
Google with their acquisition of On2 and was
open sourced on May 19, 2010. The
VP8 codec was licensed under a
BSD license. ==References==
