#
15-
# v3.344s
15+
# v3.345s
16
# - work with SMDegrain_KNLMeansCL now to process chroma too
17
#
18
# v3.343s
19
# - edit in ChromaEdi
20
# - others
21
#
22
# v3.34s (mod) 2016 12 18 (ravewulf idea in another way)
23
# - Added yadifmod2 (if you need old one use it like this EdiMode="cYadif" or EdiMode="RepcYadif")
24
# - fast and clean up YUY2 (will work in x64 now, no need to SSETools)
25
#
26
# v3.33s (mod) 2016 12 06
27
# - Add TR2=4 and TR2=5
28
# - add TV_range bool and dither_luma_rebuild (from SMDegrain) Str and Amp
29
# - for avsplus now QTGMC_Bob is ready for any 420, not only yv12
30
#
31
# v3.33s (mod) 2016 04 11
32
# - Add KNLMeansCL as another Denoiser to NoiseProcess
33
# - others
34
#
35
# v3.33s (mod) 2016 01 19
36
# - make QTGMC_deflate/QTGMC_inflate work with YUY2 using masktool2 for avs 2.60
37
#
38
# v3.33s (mod) 2015 10 23
39
# - revert to QTGMC_deflate/QTGMC_inflate quoted from Dogway
40
#
41
# v3.33s (mod) 2015 9 10
42
# - fix Multiple QTGMC Calls
43
# - others fix
44
#
45
# v3.33s (mod) 2015 8 6
46
# - some changes in bob to speed up
47
#
48
# v3.33s (mod) 2015 8 4
49
# - fix bug in YUY2 with SourceMatch
50
# - add slice=false to ditherpost to avoid artefacts
51
#
52
# v3.33s (mod)
53
# - fix bob chroma
54
# - work with new masktool2 for avs 2.60 in YUY2
55
#
56
# v3.33d (mod)
57
# - Added 32 bit precision option through the lsbd (for dfttest and knlmeanscl) and lsb (mdegrain) options.
58
# - optimized some mask handling a bit as originally suggested by Vit
59
# - others
60
#
61
# v3.33
62
# - 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
63
# - Bug fix for the fact that Bob always outputs a BFF clip regardless of field order of input (thanks ajp_anton)
64
# - Improved generation of noise (NoiseDeint="Generate") for noise bypass / EZKeepGrain
65
# - Minor change to denoising
66
#
67
# v3.32
68
# - Bugfix with shutter blur and ChromaMotion (thanks Heaud)
69
# - Tweaked vector recalculation for shutter motion blur
70
# - Changed defaults for TR2 when using source-match
71
# - Minor bugfix with SLMode/SLRad on pass-through settings
72
#
73
# --- REQUIREMENTS ---
74
#
75
# Input colorspaces: YV12, YUY2, others as plugins supports
76
#
77
# Core plugins:
78
#	MVTools2 (2.7.5.22 or above from pinterf https://github.com/pinterf/mvtools/releases)
79
#	MaskTools v2 (2.0b1 or above)
80
#	NNEDI3 (0.9.4.6 or above)
81
#	RgTools
82
#
83
# Additional plugins:
84
#	NNEDI2, NNEDI, EEDI3, EEDI2, TDeInt - if selected directly or via a source-match preset
85
#	yadifmod2 - for Preset="Ultra Fast" or if selected directly
86
#	FFT3DFilter - if selected for noise processing
87
#	dfttest (1.9.4 or above) - if selected for noise processing
88
#		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
89
#		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
90
#   KNLMeansCL - if selected for noise processing
91
#	AddGrainC - if NoiseDeint="Generate" selected for noise bypass
92
93
94
# --- GETTING STARTED ---
95
#
96
# Install AviSynth and ensure you have at least the core plugins listed in the requirements section above. Put them in the plugins autoload folder.
97
# To use QTGMC write a script like this:
98
#	YourSource("yourfile")   # DGDecode_mpeg2source, FFVideoSource, AviSource, whatever your source requires
99
#	QTGMC( Preset="Slow" )
100
#	SelectEven()             # Add this line to keep original frame rate, leave it out for smoother doubled frame rate
101
#
102
# Save this script with an ".avs" extension. You can now use it as an AVI source for encoding.
103
#
104
# The "Preset" used selects sensible settings for a given encoding speed. Choose a preset from:
105
#	"Placebo", "Very Slow", "Slower", "Slow", "Medium", "Fast", "Faster", "Very Fast", "Super Fast", "Ultra Fast" & "Draft"
106
# The default preset is "Slower"
107
# 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)
108
# For much faster speeds read the full documentation, the section on 'Multi-threading'
109
#
110
# There are many settings for tweaking the script, full details in the main documentation. You can display settings currently being used with "ShowSettings":
111
#	QTGMC( Preset="Slow", ShowSettings=true )
