#
# --- LATEST CHANGES ---
#
# v3.357s
# - high bit depth now basically work in avs+
#
# v3.354s
# - added optional chikuzen PlanarTools for YUY2 using nonyuy2clipin/nonyuy2clipout in AnimeIVTC() v2.20
#
# v3.353s
# - added ndjamena suggestion for maximum temporal radius
# - added DftDither to controle dfttest dither Parameter
#
# v3.352s
# - added useEdiExt
# - added tr0=-1 to use the EdiExt clip (if there is no EdiExt clip then it will not work)
# - rep0 now will be 0 if tr0 < 1
#
# v3.347s
# - fix SourceMatch (bug after new YUY2 method, thanks to ndjamena for report it)
#
# v3.346s
# - EEDI3+NNEDI3 bug fix by ndjamena
# - Renamed DftThreads parameter to FftThreads, to set the ncpu argument of FFT3DFilter (from VS)
# - FFT3DFilter will work now in YUY2, use it with Denoiser="fft3df" (or use NoisePreset)
#
# v3.345s
# - work with SMDegrain_KNLMeansCL now to process chroma too
#
# v3.343s
# - edit in ChromaEdi
# - others
#
# v3.34s (mod) 2016 12 18 (ravewulf idea in another way)
# - Added yadifmod2 (if you need old one use it like this EdiMode="cYadif" or EdiMode="RepcYadif")
# - fast and clean up YUY2 (will work in x64 now, no need to SSETools)
#
# v3.33s (mod) 2016 12 06
# - Add TR2=4 and TR2=5
# - add TV_range bool and dither_luma_rebuild (from SMDegrain) Str and Amp
# - for avsplus now QTGMC_Bob is ready for any 420, not only yv12
#
# v3.33s (mod) 2016 04 11
# - Add KNLMeansCL as another Denoiser to NoiseProcess
# - others
#
# v3.33s (mod) 2016 01 19
# - make QTGMC_deflate/QTGMC_inflate work with YUY2 using masktool2 for avs 2.60
#
# v3.33s (mod) 2015 10 23
# - revert to QTGMC_deflate/QTGMC_inflate quoted from Dogway
#
# v3.33s (mod) 2015 9 10
# - fix Multiple QTGMC Calls
# - others fix
#
# v3.33s (mod) 2015 8 6
# - some changes in bob to speed up
#
# v3.33s (mod) 2015 8 4
# - fix bug in YUY2 with SourceMatch
# - add slice=false to ditherpost to avoid artefacts
#
# v3.33s (mod)
# - fix bob chroma
# - work with new masktool2 for avs 2.60 in YUY2
#
# v3.33d (mod)
# - Added 32 bit precision option through the lsbd (for dfttest and knlmeanscl) and lsb (mdegrain) options.
# - optimized some mask handling a bit as originally suggested by Vit
# - others
#
# v3.33
# - Increased maximum value for Rep0, Rep1 and Rep2 to 7 (from 5). Higher values help with flicker on static detail, potential for minor motion blur
# - Bug fix for the fact that Bob always outputs a BFF clip regardless of field order of input (thanks ajp_anton)
# - Improved generation of noise (NoiseDeint="Generate") for noise bypass / EZKeepGrain
# - Minor change to denoising
#
# v3.32
# - Bugfix with shutter blur and ChromaMotion (thanks Heaud)
# - Tweaked vector recalculation for shutter motion blur
# - Changed defaults for TR2 when using source-match
# - Minor bugfix with SLMode/SLRad on pass-through settings
#
# --- REQUIREMENTS ---
#
# Input colorspaces: YV12, YUY2, others as plugins supports
#
# Core plugins:
#	MVTools2 (2.7.5.22 or above)
#	MaskTools2 (v2.2.5 or above)
#	NNEDI3 (0.9.4.6 or above)
#	RgTools
#
# Core scripts:
#	SMDegrain (3.1.2.91s or above) unless you set tv_range=false
#	AnimeIVTC (2.20 or above) if you work with YUY2 source
#
# Additional plugins:
#	NNEDI2, NNEDI, EEDI3, EEDI2, TDeInt - if selected directly or via a source-match preset
#	yadifmod2 - for Preset="Ultra Fast" or if selected directly
#	FFT3DFilter - if selected for noise processing
#	dfttest (1.9.4 or above) - if selected for noise processing
#		For FFT3DFilter & ddftest you also need the FFTW3 library (FFTW.org). On Windows the file needed for both is libfftw3f-3.dll. However, for FFT3DFilter
#		the file needs to be called FFTW3.dll, so you will need two copies and rename one. On Windows put the files in your System32 or SysWow64 folder
#	KNLMeansCL - if selected for noise processing
#	AddGrainC - if NoiseDeint="Generate" selected for noise bypass
#	chikuzen PlanarTools - if you work with YUY2 source (not necessarily required but may improve speed)


# --- GETTING STARTED ---
#
# Install AviSynth and ensure you have at least the core plugins listed in the requirements section above. Put them in the plugins autoload folder.
# To use QTGMC write a script like this:
#	YourSource("yourfile")   # DGDecode_mpeg2source, FFVideoSource, AviSource, whatever your source requires
#	QTGMC( Preset="Slow" )
#	SelectEven()             # Add this line to keep original frame rate, leave it out for smoother doubled frame rate
#
# Save this script with an ".avs" extension. You can now use it as an AVI source for encoding.
#
# The "Preset" used selects sensible settings for a given encoding speed. Choose a preset from:
#	"Placebo", "Very Slow", "Slower", "Slow", "Medium", "Fast", "Faster", "Very Fast", "Super Fast", "Ultra Fast" & "Draft"
# The default preset is "Slower"
# Don't be obsessed with using slower settings as the differences can be small. HD material benefits little from extreme settings (and will be very slow)
# For much faster speeds read the full documentation, the section on 'Multi-threading'
#
# There are many settings for tweaking the script, full details in the main documentation. You can display settings currently being used with "ShowSettings":
#	QTGMC( Preset="Slow", ShowSettings=true )
