TrueMotion VP7 is a video codec developed by On2 Technologies as a successor to earlier efforts such as VP3, VP5 and TrueMotion VP6. 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.[citation needed] However, the objective measurements used by On2 Technologies do not correlate perfectly with subjective quality measurements.
On2 Technologies announced TrueMotion VP7 in January 2005.[1] The public release of VP7 codec software was available in March 2005.[2]
In April 2005, On2 Technologies licenses On2 Video Codecs (including VP6 and VP7) for Macromedia Flash.[3]
In December 2005, Skype announced that they had selected the VP7 codec for point-to-point video conferencing.[4]
Move Networks is also using the VP7 codec in its Move Media Player plugin for Firefox and Internet Explorer, currently used by ABC and Fox for its streaming of full network shows.[5]
