A few techniques: how I restore black and white videos before colorization

Here are some techniques I used for cleaning and denoise & degraine and sharpening the black and white videos before colorization that I publish on my channel, Here are the tool and software used: Avisynth Davinci resolve Here are the avisynth scripts I used: #cleaning SpotLess(RadT=6, ThSAD2=900, pel=4, chroma=true) #Denoising and #Degraining super = MSuper(pel=2, sharp=1) bv1 = MAnalyse(super, isb = true, delta = 1, overlap=4) fv1 = MAnalyse(super, isb = false, delta = 1, overlap=4) bv2 = MAnalyse(super, isb = true, delta = 2, overlap=4) fv2 = MAnalyse(super, isb = false, delta = 2, overlap=4) MDegrain2(super,bv1,fv1,bv2,fv2,thSADC=800, thSAD=800) return last FFT3DFilter(sigma=3.0, beta=1.0, plane=4, bw=16, bh=16, ow=8, oh=8, bt=3, kratio=3.0, sharpen=1.0, scutoff=0.3, svr=1.0, smin=4.0, smax=30.0, measure=true, interlaced=false, wintype=0, degrid=1.0, dehalo=1.0, hr=2.0, ht=50.0) #Sharpen aWarpSharp2(thresh=180, blur=3, type=0, depth=35, depthC=10, chroma=4)
