Description

This script builds on Temporal Degrain but it is able to clean the noise even further while impoving the sharpness in cases where orignal version had severe drops in visual quality.

Comparing to the original version there are improvements in the motion estimation by using the exceptional approach of QTGMC and an optional final step of FFT and dithering to further smooth the output. The performance will be especially better in regions of low contrast and diverging movement where the very mushy intermediate stream was losing motion vectors thus smearing the output considerably.

The result can be completely noiseless, perfectly sharp, much better compressable, without introducing any banding while still yielding a very natural look.
