(if possible) (/thread-4029.html)

How is called this kind of "defect" and how to mitigate? (if possible) - Bartoloni - 06.03.2025 this is what happens on final result using MCdegrainsharp and QTGCM deinterlace.. on the original footage is not too much visible but after the degrain is very very evident. original footage: https://www.wcn.it/defect.zip the problem seems related to some sort of fast interference (generated on the TBC) and red seems more influenced from it. the strange thing is that just on this tape is very very evident. very thnak you for any help! RE: How is called this kind of "defect" and how to mitigate? (if possible) - Selur - 06.03.2025 Looks like some kind of aliasing. 1rst idea try: 1. denoising the separate fields before deinterlacing/ivtc. 2. applying Santiag with increased strength afterward. will look at it after work. Cu Selur RE: How is called this kind of "defect" and how to mitigate? (if possible) - Selur - 06.03.2025 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. Cu Selur RE: How is called this kind of "defect" and how to mitigate?
