    This is the Australian retail DVD release of Dilbert, it's formatted as NTSC and I'm pretty sure it was sourced from a video tape. It's full of noise and the lines are absolute crap that jitter-bleed??? into the adjoining pixels.

    Sorry, it's 160mb because I wasn't sure what was relevant
    http://www.mediafire.com/download/bj8578wkzil1jnw/sample.mkv

    This is the best Script I've got so far:

    Code:
    SetMemoryMax(768)
    SetMTMode(5,6)
    MPEG2SOURCE("sample.d2v")
    AnimeIVTC(mode=1)
    Crop(6,4,-6,-4)
    SetMTMode(2)
    FFT3DFilter(sigma=6, plane=4).Toon().blur(1.58).sharpen(1)
    FFT3DFilter(sigma=4, plane=4).Toon().blur(1.58).awarpsharp2(Thresh=128, Type=1, depth=16)
    Toon().blur(1.58).sharpen(1)
    Toon().blur(1.58).sharpen(1)
    TemporalSoften(5,10,15,10,2)
    ColorYUV(off_y=32)
    Toon()
    ColorYUV(off_y=-32)
    Toon()
    DAA3()
    Don't ask me how I got there, I think I knew what I was doing when I was doing it but now I'm kind of lost. At the moment every modification I try either does nothing or makes it worse. The script fixes the worst of the problems but parts of the lines disappear or fade too much where there was too much interference around it and the text after the title sequence have been ruined. There's also a scrabble board later in the episode that gets turned into a black mess. I've experimented with edgecleaner but it did nothing.

    Before I spend the next few days encoding these episodes I thought I'd ask if anyone can write a better script to fix this.

  2. This is definitely a case where less is more.

    Code:
    SetMTMode(5,6)
    Mpeg2Source("sample.d2v", CPU=6, Info=3) 
    SetMTMode(2)
    CheckMate()
    TFM()
    TDecimate()
    FFT3DFilter(sigma=4, plane=4).awarpsharp2(Thresh=128, Type=1, depth=5)
    That does leave some chroma rainbows but it's much less destructive to the rest of the picture.

    Quite possibly, dotcrawl, huh. I'll have to try that but I don't have checkmate and the three links I've found for it all lead to the same dead end

    He could use camera color denoise (in vdub very fast by the way) and do chroma denoising there, and use fft3d for luma only.

    checkmate mirror

    It's one of those dll's where there is no included documentation, but you can read about some of the settings here

    Is that Color Camcorder Denoise? That's all Googling 'camera color denoise virtualdub' gives me.

    The filter itself is ccd.vdf. It's in a download called ccd.zip. Get it here: http://acobw.narod.ru/file/ccd.zip . Its name is Camcorder Color Denoise.

    Be careful with it and check the results. It works OK most of the time; it can clean some chroma artifacts but sometimes creates new ones.
