After having another play, I'm still at a loss as to why field matchers/deinterlacers think the progressive frames need deinterlacing and why they make such a mess of it when they do, but for re-encoding.....

What seems to work for the sample at least, is to use much less enthusiastic field matching than TFM's defaults and to back off the combing detection quite a lot. The easiest way to do the former is to use TDeint instead of TFM, and they both have the MI argument.

This fails to find a match for the orphan fields around the scene changes so it de-interlaces them instead, which IMHO is better than duplicate frames.

TDeint(MI=200, TryWeave=true)

Trouble is, there's somehow aliasing built in anyway, and even denoising seems to make it worse, and anti-aliasing tends to blur so I'd sharpen to counter-act it, and of course I'd also be keen not to sharpen noise much....

Both screenshots are the script output upscaled to 1080p by MPC-HC.

Code:

FFVideoSource("E:\soft telecine.mkv", FPSNum=24000, FPSDen=1001, threads=1)
CropResize(0,0, 9,0,-7,0, InDAR=15.0/11.0, ResizeWO=true)
