#-------------------------------------------------------------------# # # # 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.
