For leftover artifacts from bad deinterlacing, use QTGMC (the gold standard for anime). In VapourSynth or AviSynth:
import vapoursynth as vs
core = vs.core
clip = core.ffms2.Source("input.mkv")
clip = core.qTGMC.QTGMC(clip, Preset="Fast", TFF=True)
clip = core.resize.Bicubic(clip, format=vs.RGB24)
clip.set_output()
This removes all field-based ghosting. For compression-based nokotowo, use hqdn3d filter: shinseki nokotowo tomari dakara animation fix
ffmpeg -i input.mkv -vf "hqdn3d=4:3:6:4" -c:v libx264 output_denoised.mkv
