    Hello! I'm trying to deinterlace this source from a PAL DVD but this is difficult achieving that because this source is only interlaced from certain scenes
    and progressive on the other scenes (It's not any pull down that has to be TDecimate)
    Most of the deinterlacers failed me by giving insane jagged line artifacts, the best I got is NNEDI3 which works really great on the interlaced scenes
    but gives me jagged lines artifacts (Not as bad as the others) on progressive scenes.
    Can anyone help me out here? Thanks!

  2. That clip is encoded interlaced but all frames are progressive.

    Code:
    LWLibavVideoSource("B1_t01_1.mkv", cache=false, prefer_hw=2) 
    AssumeTFF()

    Sorry, I should've trimmed a sample with both interlaced and progressive scenes

  4. Most of it is 25p but some zooms and other effects are 25i (50 different pictures per second). QTGMC doesn't do too badly.

  5. Just for fun I threw a qtgmc, (edgemasked) BasicVSR++, some sharpening and line darkening at it.
    script
    to see whether something like:

    can be fixed.

    This doesn't look good at all, like a said from a earlier post,
    QTGMC doesn't work good with SD animated content since it gives out tons of motion from duplicated frames than it should be as well with some loss of detail leaving black particles in some frames. I don't really need much filtering besides deinterlacing which is a pain to do with a source like this, but thanks for trying to help.

  7. There are also places where there is uneven motion from field to field. For example, instead of the pan or zoom moving 10 pixels per field, 10 20 30 40 50 60 70... it moves in uneven increments like 10 12 30 32 50 52 60... This is responsible for some of the problems.
