  1. I am using QTGMC, and for some reason when things are in motion, I am seeing a half invisible artifact, which is a piece of the next or previous frame. Almost as if it is a piece of blending.

    Code:
    QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", fpsdivisor=2, sourcematch=3)
    Here is an example.

    If I do not deinterlace at all, or I use TIVTC which sucks on this particular source, I do not get those artifacts.
    I have tried changing multiple settings and parameters, but I have had no luck. Is this something I will just have to deal with?

    Maybe try turning off the temporal denoisers. http://avisynth.nl/index.php/QTGMC#Noise_Bypass_.2F_Denoising Or switch to very slow for better temporal denoising.

  3. I tried both of those. It does not seem to fixing it for me.

    Perhaps someone can suggest a better deinterlacing setting for TFM? The TIVTC/TFM has a lot of leftover artifacts.
    tfm(order=1).tdecimate(mode=1,hybrid=0)

    Here is a sample video.

    If you are out of options, I would also try going back to an older version like 3.32 (~2015). http://forum.doom9.org/showthread.php?t=156028 I have not done any tests personally but in the past years I've had the hunch that QTGMC has gotten worse over the years with artifacts.

  6. 3.32 is actually the one I am using.

    I just decided I'll live with it. I spent a good 3 hours trying tons of combinations of settings and nothing I tried stopped it. When the video is on motion, you don't even see the artifacts. You have to know about them, be looking for them, or pause at just the right time to even see them on playback, so I'll live with it.

    I got tfm with clip2 to work, and it didn't have the artifacts, but I went with the QTGMC and thought it looked better overall.
    tfm(order=1, clip2=QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", FPSDivisor=2, sourcematch=3, tr1=2, tr2=2, NoiseTR=2), cthresh=4, mi=31)

    Thanks for the suggestions though.
