Motion Pixels version 1 (MVI1) was used in a single PC game, Treasure Quest while version 2 (MVI2) was used in a number of Movie CDs. All of these items were published by Sirius Publishing and the Motion Pixels codec is believed to still be owned by the company's CEO, Richard Gnant.
MVI belongs to the "old-school" family of video codecs and relies on interframe differences and adaptive delta-coding for horizontal lines of the picture. Delta coefficients are additionally Huffman-packed. For better compression at the cost of picture quality additional colorspace downsampling may be used. MVI2 adds smoother delta-coding and the ability to dynamically change downsampling for each frame.
Compressed MVI1 video may be carried in the custom MVI Container format.
