# Small Deflicker 2.4
# Based in idea by Didée, kurish (http://forum.doom9.org/showthread.php?p=1601335#post1601335)
# Adapted by GMJCZP
# Requirements:
# Masktools: https://github.com/dubhater/vapoursynth-mvtools
# RemoveGrain: https://github.com/vapoursynth/vs-removegrain
# Cnr2: https://github.com/dubhater/vapoursynth-cnr2
# MSmooth: https://github.com/dubhater/vapoursynth-msmoosh
# TemporalSoften2: https://github.com/dubhater/vapoursynth-temporalsoften2
# SceneChange: https://forum.doom9.org/showthread.php?t=166769
# USAGE:
# Small_Deflicker(clip, width_clip=width(clip)/4, height_clip=height(clip)/4, preset=2, cnr=False, rep=Dalse) (default values)
# PRESETS:
# preset = 1 Soft deflickering (GMJCZP values)
# preset = 2 Medium deflickering (kurish values, preset by default)
# preset = 3 Hard deflickering (Didée values)
# REPAIR MODE:
# - Chroma noise reduction it is an experimental attempt to mitigate the side effects of the script
# By default it is disabled (only for presets 2 and 3)
# - Repair is an option for certain sources or anime/cartoon content, where ghosting may be evident
# By default it is disabled (maybe for preset = 1 it is not necessary to activate it)
