# #
# QTGMC 3.31, by Vit, 2011 #
# #
# A high quality deinterlacer using motion-compensated temporal #
# smoothing, with a range of features for quality and convenience #
# Originally based on TempGaussMC_beta2 by Didée #
# #
#-------------------------------------------------------------------#
# Full documentation is in the 'QTGMC' html file that comes with this script
# --- LATEST CHANGES ---
#
# 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
#
# Core plugins:
# MVTools2 (2.5.11.2 or above)
# MaskTools v2 (recommend 2.0a45 or above. Must use the 2.5 version with YUY2)
# NNEDI3 (recommend 0.9.2 or above)
# RemoveGrain + Repair
#
# Additional plugins:
# NNEDI2, NNEDI, EEDI3, EEDI2, TDeInt - if selected directly or via a source-match preset
# Yadif - for Preset="Ultra Fast" or if selected directly (cannot be autoloaded, must be loaded in the calling script)
# VerticalCleaner - for SVThin or Lossless modes
# FFT3DFilter - if selected for noise processing
# dfttest - 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
# AddGrainC - if NoiseDeint="Generate" selected for noise bypass
# --- 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". If you get crashes with the fastest presets ("Super Fast" and above)
# Don't be obsessed with using slower settings, the differences can be small. In particular HD material benefits less from extreme settings (and will be 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 )
