TrueMotion
On2 TrueMotion Video Compression is a set of formats for lossy compressed video data and associated video codecs that were developed and sold by former On2 Technologies Inc.
history
According to the manufacturer, development began in the early 1990s. The first versions of the format were mainly aimed at use for FMV sequences in computer games and were used accordingly. Therefore, they were specially designed for limited resource requirements. Even later versions of the codec were quite economical in terms of computing requirements compared to the current main competitors. Initially, there were only hardware implementations of the codec that only ran on special hardware modules.
TrueMotion-S
TrueMotion S (also known as TrueMotion 1.0 ) was released towards the end of 1993 when the company was still called The Duck Corporation . Starting with TrueMotion-S ("S" for "software"), Duck switched to pure software implementations that run on normal general-purpose processors. The format was used in the 1990s for FMV sequences in computer games of the second CD-ROM-based game consoles ( 5th generation , for example Sega Saturn ) and also in some PC games (for example Batman Forever).
TrueMotion-S data usually come in AVI containers with the FourCC codec ID DUCK(or PVEZ, under certain circumstances TMOT) in files with the extensions .avi, .bin or .duc. The software library libavcodec of the FFmpeg project contains a free decoder for the format.
TrueMotion RT
("RT" for "real time", German: real time ) was published in 1996. It was intended for real-time recording and processing of digital video material.
TrueMotion 2
FourCC: TM20was used in Final Fantasy 7, for example
TrueMotion VP3, TrueMotion VP4
FourCC: VP30, VP31, VP32;VP40
VP3 is a format optimized for streaming at low bit rates. libavcodec includes a free decoder for the format. The code base of VP3.2 represents the basis of the (patent) free format Theora of the Xiph.Org Foundation .
Metavisual , founded by Paul Wilkins (Cambridge, UK), was bought by On2 to bring VP3 to market. On June 1st, 2000, Version 3.1, which introduced a new bitstream format, came out on August 16, Version 3.2. At the end of 2001 the release as Free Software was announced. In 2002 the format was handed over to the free software community together with the source code of the reference implementations of VP3 (.2) and the associated patents of On2 and published as free software.
In April 2001 VP4 was released, which only brought an improved encoder for the same bitstream format. On2 has released VP4 for personal, non-commercial use.
TrueMotion VP5
FourCC: VP50.
A preview version of VP5 was released on February 21, 2002; Production versions were available from May 1st. libavcodec includes a free decoder for the format. It is one of the video formats intended for the Enhanced Versatile Disc (EVD).
TrueMotion VP6
VP6 was released in May 2003 and released for private, non-commercial use in October 2003. It was made the standard video format for Flash Video .
TrueMotion VP7
VP7 was released in March 2005; since July it can be used free of charge for private purposes.
TrueMotion VP8
VP8 was released in 2008. After On2 was bought by Google , VP8 was released as Free Software on May 19, 2010 and released for unconditional use.
VP9
VP9 was released in 2013. It represents the last official edition of the series. The experimental VP10 is the basis of AV1 in the video format series AOMedia Video (AVx) of the Alliance for Open Media.
