  1. one of the anime that I love is NANA (2006), I have R2J DVD (NTSC,30000/10001,868x480), those DVD suffer a lot of banding, dot noise, I used vapoursynth to fix interlace,and balance between banding and dithering

    any suggestion


    Code:
     import vapoursynth as vs
    import sys
    import importlib
    import functools
    core = vs.get_core()
    sys.path.append(r"C:\vs\VapourSynth64Portable\Scripts")

    You should IVTC and not deinterlace.

    TFM()
    TDecimate(Mode=1)

    I used that but the frame jump back and forward too much, what advantages of this over the QTMC that I used ?

    Tdecimate provides the underlying 24 fps, rather than the 30 with duplicate frames.
    Use it instead of the qtgmc.

    You had the field order wrong. Use AssumeTFF (or AssumeBFF) before the TFM call to correct it.
    what advantages of this over the QTMC that I used ?
    It will restore the framerate to its original and correct 23.976fps.

    Tried MCTemporalDenoise (default settings) perhaps this will help.
    Although at the 14-15 seconds mark, the OP's script seemed to smooth the posterization
    a little better

  9. If you just want to reduce the posterization you can use GradFun3() or GradFun2DBMod(). Then you have to encode with enough bitrate to retain the added noise. Otherwise you might as well not bother.

  10. much better any other suggestions ?
