Description

MDec2, MultiDecimate like decimating filter.

Requirements

• [x64]: AviSynth+
• Supported color formats: RGB24, RGB32, YUY2, Y8, YV12, YV16, YV24, YV411

• Microsoft Visual C++ 2008 Redistributable Package (x86 / x64)

*** vcredist_x86.exe is required for MDec2-x86

*** vcredist_x64.exe is required for MDec2-x64

Syntax and Parameters

MDEC2(clip c,float "rate"=24.0,bool "show"=false,bool "create"=false,string "dir"="C:\",bool "chroma"=true,bool "ver"=false)

MDec2 is a 2 pass decimating filter, acting much like the Multidecimate filter by Donald A. Graft.
Requires MultiDecimate.Exe & ProcessMD.Exe from MultiDecimate package.

Args:-

 c, clip. No default

 Rate=24.0, final output frame rate, used only on 2nd pass.

 show=false. 1st pass, shows metrics on frame, 2nd pass shows frame being used.

 create=false. Set true for 1st pass, false on 2nd pass after using MultiDecimate.Exe.

 dir="C:\". Path to data files (mfile.txt, cfile.txt, dfile.txt).

 chroma=true. If false then only use luma for metrics. (RGB not used).

 ver=false. True shows version on frame.

 See MultiDecimate docs for further info.

Metrics

Metrics:-
 MDec2, modified metrics based on FDecimate by Donald Graft.
 Splits frames into blocks and returns metric of block with greatest difference.
 YUV Metrics weight combined chroma with same weight as luma.

NOTE, if wanting to eg decimate 29.97 to 25.0, then numbers dont work and will throw an error because of
mismatch to what it is expecting. In such circomstance, use something like:-
>>>>>>>>>>>
    SHOW=True
    ORG=Last
    AssumeFPS(30.0,sync_audio=True)
#    ResampleAudio(ORG.AudioRate)
    Mdec2(Rate=25.0,create=True,Show=True,Dir="")    # Pass 1 [Dir="", files in current directory]
    ###
    Use MultiDecimate.Exe, eg drop 1 frame in every 6.
    ######
    SHOW=False
    ORG=Last
    AssumeFPS(30.0,sync_audio=True)
    ResampleAudio(ORG.AudioRate)
    Mdec2(Rate=25.0,create=False,Show=SHOW,Dir="")    # Pass 2, output 25 fps.
