Getting rid of purple fields

[Selur]

Okay, totally different from what I expected from the screenshot.
To get you started, you can lessen that a lot by using SpotLess with a high temoral radius (like 6) multiple interrations (i.e. 5) and only apply the chroma portion (merge: Y=0,U=1,V=1).
Here I applied that twice. (using FilterQueue instead of FilterOrder)

clipMerge = clip # Spot removal using SpotLess clip = SpotLess.SpotLess(clip, radT=6, asearch=5, pel=1, mStart=True, mEnd=True, iterations=5, tools={'mv': 'mvutensils', 'expr': 'akarin', 'tmedian': 'zsmooth', 'ttempsmooth': 'zsmooth', 'boxblur': 'std', 'hysteresis': 'hysteresis'}) clip = core.std.Merge(clipMerge,clip,[0, 1, 1]) # merge filtered and unfiltered by plane clipMerge = clip # Spot removal using SpotLess clip = SpotLess.SpotLess(clip, radT=6, asearch=5, pel=1, mStart=True, mEnd=True, iterations=5, tools={'mv': 'mvutensils', 'expr': 'akarin', 'tmedian': 'zsmooth', 'ttempsmooth': 'zsmooth', 'boxblur': 'std', 'hysteresis': 'hysteresis'}) clip = core.std.Merge(clipMerge,clip,[0, 1, 1]) # merge filtered and unfiltered by plane

But this will be really slow.
