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.

- currently just postFFT=0, 1 and 4 are supported for high bit
Feb 24, 2019: v2.2.1
- swap deprecated use of ConvertToXbit by ConvertBits
- relaxed settings for scene change detection, was too aggressive
Apr 12, 2019: v2.2.2
- refine input size categorization
Feb 02, 2021: v2.2.3
- rescale SAD/SCD thresholds when DCT is switched from SAD to SATD
- allow change of motion estimation also based on chroma (meChroma)
Feb 02, 2021: v2.2.4
- use optional high bitdepth processing for FFT3DGPU

Feb 07, 2021: v2.3.0
- use native high bit format also for KNLMeansCL
- scale sigma of FFT3DGPU
- grainLevel is now interger range 0-2
- make setup of grainLevel easier by using parameter grainLevelSetup=true
- provide user with the choice which stage of the pipeline to output (outputStage)
Feb 07, 2021: v2.3.1
- tune grainLevel 1 to fit more centrally between 0 and 2
- reorganize arguments by importance
Dec 16, 2021: v2.3.2
- go back to using SAD (DCT=0) instead of SATD, since SATD appears to make more harm then helping
- tweak usages of FFT3DGPU to match the FFT3DFilter usages (thanks goes to Tenkei)
- HQdn3D does now support high bitdepth
- KNLMeansCL correct sigma to match the other filters (factor 2 higher then before)
Dec 19, 2021: v2.3.3
- set thSADC to be half of thSAD, since changes in chroma are usually smaller than in luma
Dec 20, 2021: v2.3.4
- dithering is delayed to after contraSharpending which increases quality of dithering, decreasing banding and noise (postDither=2), old behaviour is regained with postDither=1
- postDither argument has been inverted! [new postDither = (-1) * old postDither]
Dec 21, 2021: v2.4.0 (This and later releases need AviSynth 3.7.1+)
