It has the best compression ration among free lossless Vidéo codecs. Supports RGB, YUY2 and YV12. Allows to set up speed/compression ratio compromise by choosing appropriate motion compensation algorithm. Allows to set up loss/compression ratio compromises. Performs accurate denoisng in temporal and spatial domains during lossy compression. Denoising offten improves quality of Vidéo.
