    It makes me mad...Masters,Please help me!Thanks!

    Code:
    MPEG2Source("C:\BONUS_DVD\VIDEO_TS\xw_temp\xw.d2v",info=3)
    ColorMatrix(hints=true,interlaced=true)
    ConvertToYV12()
    AssumeTFF()
    tdecimate(mode=0)
    QTGMC(preset="Very Slow", FPSDivisor=2,sourceMatch=2, tr2=2, EZDenoise=2, DenoiseMC=true)
    vInverse()
    MergeChroma(aWarpSharp(depth=20))
    BicubicResize(640, 480)

  2. I don't see any comb artifacts in your sample image. I think you just have normal YV12 chroma subsampling issues. But...

    ConvertToYV12() should be ConvertToYV12(interlaced=true) because the video is interlaced at that point. But it shouldn't make any difference here because the output of Mpeg2Source() should already be YV12 -- so the filter won't do anything. Also, it makes no sense to TDecimate() before deinterlacing or IVTC'ing.

    I recommend you use Dgindex to demux a short sample of your source and upload the resulting M2V file.

    Thanks for your replying.Here is the original m2v file:
    https://files.videohelp.com/u/245858/___.demuxed.m2v

    According to your advice,I change my code:
    Code:
    MPEG2Source("C:\BONUS_DVD\VIDEO_TS\飞轮海 S.H.E. 新窝_temp\飞轮海 S.H.E. 新窝.d2v",info=3)
    ColorMatrix(hints=true,interlaced=true)
    ConvertToYV12(interlaced=true)
    QTGMC(preset="Very Slow", FPSDivisor=2)
    tdecimate(mode=1)
    Spline64Resize(640, 480)

  4. The problems in your image are from poor deinterlacing and chroma subsampling.

    The video is a mix of telecined film, badly deinterlaced telecined film, and some badly deinterlaced 30i video. To get the best results you would have to filter the different sections individually. But here's a compromise script that works pretty well for most of the video.

    Code:
    Mpeg2Source("___.demuxed.d2v", CPU2="ooooxx", Info=3) 
    TFM(d2v="___.demuxed.d2v", field=0, cthresh=4) 
    TDecimate()
    QTGMC(InputType=2)
    Some of the animated sequences get a little mess up by this though (for example, the shoe laces about 14 seconds into the clip).

    Thx for your guide.I think your idea is good but the result is simlar to mine.Maybe the bad quality of my sourse cause these defect.
    Still thanks for your helping.There are too much to learn about ripping.
