    I've been trying to use QTGMC on SD animation content (Mostly from DVD's) and it's been giving me some weird motion artifacts every time,
    When I mean by "motion artifacts", I mean by ghosting, random blackspots, and some weird moving that you can see when comparing two frames apart (I don't know the exact word for that one).

    I can't find a script that fixes this issue without resizing to 1080p which fixes the problem.

    (I used Bilinear to resize to 1080p on the resized image)
    It's fine if I resize to 1080p, I just wanna know what's causing this issue and fix it with the new script.
    Can anyone help me out here? Thank you!
    (Note: This is the QTGMC script I use for normal 1080p/1080i content, which fixes most of the ghosting and some black parts, but not any of the weird moving I mentioned before
    Code:
    QTGMC(preset="Placebo", TR0=2, TR1=2, TR2=3, Rep0=1, Rep1=0, Rep2=5, EdiMode="EEDI3", InputType=2, NoiseRestore=1.0, NoiseProcess=1, Sigma=1.4, StabilizeNoise=True)

    And this is the script I used for the original size on the first image
    Code:
    QTGMC(InputType=3)

  2. InputType=2 turns off the deinterlacing. It's normally used to clean up a video that's already been poorly deinterlaced. So there's no wonder why your getting lots of problems. Using your QTGMC settings to clean up after an IVTC:

    Code:
    LWLibavVideoSource("QTGMC_Motion_Artifacts_sampleoriginal.mkv", cache=false, prefer_hw=2) 
    AssumeTFF()
    TFM()
    TDecimate()
    QTGMC(preset="Placebo", TR0=2, TR1=2, TR2=3, Rep0=1, Rep1=0, Rep2=5, EdiMode="EEDI3", InputType=2, NoiseRestore=1.0, NoiseProcess=1, Sigma=1.4, StabilizeNoise=True)

    Forgot to mention this on the post, but I was using AssumeTFF(), TFM(), TDecimate() with QTGMC (There's nothing else on the script besides those 4) seen on the images I posted before, Sorry, I should've been more specific on the script I was using,
    and too be more specific on the motion artifacts I'm talking about, I encoded the same scenes with and without QTGMC to tell the difference apart.
    Without QTGMC (QTGMC Script): https://drive.google.com/file/d/1MOgT_fMZkaQ6tK2iEYdE7EzQqYtCRVxE/view?usp=sharing
    With QTGMC (TFM Script): https://drive.google.com/file/d/1SE1-sl7Wmx-gWn1nfnd_75X8Qs9I7Y7S/view?usp=sharing
    Take a look at 00:26 on the QTGMC script, see how there's way more movement compared to the TFM script, yeah, that's not supposed to happen,
    and I need that movement bug to be fixed (If it's possible).

  4. Try adding Lossless=2 or Lossless=1 to your QTGMC call,...
    using the QTGMC_Motion_Artifacts_sampleoriginal source with TFM, TDecimate und QTGMC:
    Lossless=0

    Lossless=1

    Lossless=2

    with Lossless=0, ghosting from the previous frame is visible in the trouser and under the table.
