How is called this kind of "defect" and how to mitigate? (if possible)

Here's what that first idea does:

# converting interlaced to half-height progressive for filtering (vsMCTemporalDenoise) (separate fields) clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="limited") clip = core.std.SeparateFields(clip, tff=False) clipEven = clip[::2] # resolution 720x288 clipEven = core.std.SetFrameProps(clip=clipEven, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive clipOdd = clip[1::2] # resolution 720x288 clipOdd = core.std.SetFrameProps(clip=clipOdd, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive # denoising using MCTemporalDenoise clipEven = denoise.MCTemporalDenoise(i=clipEven, settings="very high", ncpu=10) # denoising using MCTemporalDenoise clipOdd = denoise.MCTemporalDenoise(i=clipOdd, settings="very high", ncpu=10) # converting half-height progressive to interlacedbefore deinterlacing clip = core.std.Interleave([clipOdd, clipEven]) clip = core.std.DoubleWeave(clip=clip, tff=False) # resolution 720x576 clip = core.std.SelectEvery(clip, 2, 0) clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_TOP) # tff # Deinterlacing using TIVTC clip = core.tivtc.TFM(clip=clip, chroma=True) clip = core.tivtc.TDecimate(clip=clip, mode=7, rate=23.9760, dupThresh=0.04, vidThresh=3.50, sceneThresh=15.00)# new fps: 23.976 # Making sure content is preceived as frame based clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive # applying anti aliasing using santiag clip = antiAliasing.santiag(c=clip, strh=3, strv=3, nns=2, qual=2, pscrn=2, opencl=True)

clip

2nd idea: using SpotLess before the deinterlacing and BasicVSR++ on the edges after Santiag. (script,clip)
3rd idea: adding CodeFormer to before BasicVSR++ (script,clip)

Hope these help to get it started.
