Trying to figure out if I can get rid of these "wire mesh" artifacts.

[LaserBones]

I've included an image and an unfiltered clip from the DVD I'm encoding. The DVD is 25fps PAL. Most of the footage is progressive but it does have some interlaced live action section so I'm currently using the script below. You'll notice the footage has a "wire mesh" artifact. The entire series has these artifacts. IS there anyway to resolve this?

q = QTGMC(TR0=2, TR1=2, TR2=1, Rep0=1, Rep1=0, Rep2=4, DCT=5, ThSCD1=300, ThSCD2=110, SourceMatch=3, Lossless=2, Sharpness=0.3, Sbb=0, MatchPreset="slow", NoiseProcess=2, GrainRestore=0.0, NoiseRestore=0.4, NoisePreset="slow", StabilizeNoise=false, NoiseTR=0, NoiseDeint="bob", EdiThreads=4)#.Subtitle("QTGMC") # for debugging purposes, remove subtitle for production
d = ChangeFPS(50)
ConditionalFilter(d, q, d, "IsCombedTIVTC(cthresh=2)")

you could for example use KNLMeansCL

KNLMeans(d=0,h=10)

and later add some line darkening, luma sharpening,...
Downside is loosing fine details, see clouds,...

Another approach would be using RemoveDirtMV and some Sharpener.

Ps.: Instead of QTGMC, I would just use TFM for the combed parts.
PPs.: as alternative to KNLMeansCL one could also use HQDN3D with high values (temporal luma should be 0 or at least small).
PPs.: DPIR denoise with a strength of 25 or so will also work. (but also loose lots of small details)
