    I got a DVD whose quality is bad.It's hard to understand how I can deinterlace it for me.
    Please check it,masters.Please give me a hand,thanks!

  2. It's not interlaced so it doesn't need deinterlacing. Maybe it needs anti-aliasing with Santiag or some such. Maybe it needs some cleanup with QTGMC(InputType=2).

    That's interesting because Mediainfo reports it as Interlaced, TFF:

    Bobdoubler in VDub is smooth for both.

    Here's my effort, QTGMC Inputtype=1, light ezdenoise, Santiag anti aliasing, sharpened the Chinese characters at the bottom.
    Encoded in Virtualdub2, 8 bit x264, preset slow, CRF18, tune=film

    Virtually all PAL DVDs are encoded as interlaced. That says nothing about the actual content. And if you do put on a bob filter and then check a section with movement, you'll notice that every frame has a duplicate. If it were really interlaced, every frame would be different.

    Thanks. So Mediainfo gets it's info from the "encoding details", not the actual file itself?

    I tried bob(), I noticed the Chinese characters at the bottom seemed to change, artifacts of some kind, or could it be traditional and simplified Chinese on alternate fields ?

    Oh,you did a great work.I know it's hard to change the quality of video,so what you did I think it's wonderful.But the Chinese lyrics of you is not good.Do you have other idea about it?
    Thanks for the video you show to me.

    Just traditional Chinese.

    The characters at the bottom are a little soft if you leave them
    As-is. Perhaps this would be your preference? If you know how to use Avisynth you can create a simple script to check the look of different sharpeners

  13. I don't know if my effort's any better or worse than davexnet's effort (I haven't downloaded it yet) but you can keep the Chinese characters out of whatever other filtering you use, or filter them separately etc.

    Even though the source is progressive, I think it's been incorrectly resized or something, and de-interlacing with QTGMC anyway seems to produce a reasonable result.

    Code:
    V = mpeg2source("D:\6wing.demuxed.d2v")
    
    A = V.QTGMC()\
    .SelectEven()\
    .MAA()\
    .FineDehalo()\
    .Crop(24, 60, -24, -60)\
    .Spline36Resize(956,456)\
    .AddBorders(0,60,0,0)\
    .GradFun3()
    
    B = V.Crop(24, 516, -24, 0)\
    .Spline36Resize(956,60)\
    .LSFMod()
    
    StackVertical(A,B)
    Edit: Looking at the text on it's own I cropped too much at the bottom and there's a few lines of the picture above included.
    "A" probably should've been Crop(24, 60, -24, -56).Spline36Resize(956,460).AddBorders(0,60,0,0)
    "B" probably should've been Crop(24, 520, -24, 0).Spline36Resize(956,56)
