TRUDEF™ Fractal Video Compression
TRUDEF™ is the successor of TMMI's SoftVideo™ fractal compression products developed in the 1990's which has evolved into the VDK3 code base supporting multi core 64 bit hardware.
TRUDEF™ Fractal Video Compression is intended for high quality native (non scaled) high resolution video for the Digital Cinema and Home Theater markets via large file based distribution on physical media.
A fractal is an object or quantity that displays self-similarity. Fractal image compression is founded on the fact that in a sequence of images blocks containing self similar patterns are repeated. TRUDEF™ Fractal Video codec is a simplified non PIFS (Partitioned Iterated Function Systems) algorithm that searches for self similar blocks within an image encoding them into data called "fractal codes". When images are viewed; fractal codes are remapped back into the correct location using self similar blocks
where matches exist.
Fractal video compression is asymmetrical in nature, encoding is resource intensive, however, playback is lightweight and fast.
TRUDEF™ Fractal Video is an effective method of playing high quality high resolution 2x2 block encoded Intra Frame video compressed in the 3-4:1 range that can be read from a single SATA3 hard drive.
RAID or SSD storage is not required. TRUDEF™ uses Intra Frame only (no data is shared between frames) which eliminates the possibility for temporal artifacts.
TRUDEF™ compresses video in the 24 bit RGB/YUV 4:4:4 color space offering a rich viewing experience compared to most common distribution codecs that down sample color to YUV 4:2:0.
TRUDEF™ has been tested with the "Magic Hour" sequence of StEM (Standard Evaluation Material) commissioned by DCI (Digital Cinema Initiative) for purposes of video codec quality analysis. This digitally scanned 35mm film saved as 4096x1714 16-bit TIFF files 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™ Fractal Video is capable of smooth playback at more than 5x the data rate as specified by the DCI for Digital Cinema (2012 250mbps JPEG 2000 2K or 4K) at 22% utilization on a 2012 Intel Core i7-3939K 3.2GHz CPU and a commodity SATA3 hard drive.
The latest version of the TRUDEF™ Video Player with VDK3 Decompressor compiled for Windows 10-64 is capable of 8K playback on 2018 commodity hardware.
