I am interest in fractal compression and would like to clarify myths and wild speculation about this technology. There are new developments taking place and I am attempting to gather enough facts and references to be included in the fractal compression article for the benefit of others who are also interested in this subject.
TruDef and SoftVideo, Fractal Compression Development Continues
High Definition Fractal Video Compression (TruDef) [1] is the only known commercial video codec under active development capable of encoding full motion video using fractal compression. Its former name was SoftVideo, a product used in a number of CD-ROM games.
Development started in the early 1990's between
While showing promise computer hardware of the time lacked the necessary processing power for fractal video compression to be practical beyond a few select usages. Compression results were only achieved by distributing encoding tasks over a network of servers and took up to 15 hours to encode a single minute of video.
With current computing technology several generations ahead, Total Multimedia Inc. announced in 2007 further development of its SoftVideo codec, renaming it to TruDef and its plans for the next generation codec conforming to modern
Latest Build: TruDef Encoder V.0.001 (June 17, 2008), Visual Studio 2008 for Vista 32, supports Multi Threading for Intel® Dual and Quad Core architecture, distributed processing over networked servers.

Evaluation
TruDef has been tested with the "Magic Hour" sequence of StEM (Standard Evaluation Material) commissioned by DCI (Digital Cinema Initiative) for purposes of quality analysis of video compression codecs. This footage contains a number of elements such as complex motion, film graining and color variations that are a better test of a video codec's capabilities.
TruDef was tested by cropping out 1600x1216 sections of the original 4096x1714 uncompressed RGB 4:4:4 24fps StEM footage providing 1.95 megapixel resolution which compressed in the 8-9mbps range.
Four test clips were made each containing 98 frames with a total file size of 15.4MB. The average 1600x1216 frame size is 39KB.

You will see from the video no human intervention is required during the encoding process, contrary to false and misleading claims previously made in the Wiki fractal compression article.

Performance
A single frame of 1280x960 4:2:0 color video takes 0.23 seconds to encode using TruDef Fractal Compression compiled for Microsoft Vista 32:
Total time to compress 552 1280x960 frame sequence: 127635 ms (4.324833 fps)
Note: Encoding time includes hard drive I/O bottleneck.
