Which denoise filter would you recommend for this video?

[orion44]

I'm backing up my DVD collection, and I would like to remove some noise from this video. Which denoise filter would you recommend for this type of noise?

Here's a screenshot:

Personnaly i use NeatVideo.

Using 1st sample vid, it isn't that grainy. Better to use player denoise function. If you must denoise then mctemporaldenoise at low setting will do the job.

I would probably go with MCDeGrainSharp.

I applied denoise script

LWLibavVideoSource("C:\Users\Alex\Downloads\Sample2.avi", stream_index=-1, cache=true, dr=false).AssumeFPS(23.976)

ConvertToYV12()
Crop(2, 0, -2, -0)
Spline144Resize(704, 528)

RemoveGrain(0)
ChangeFPS(last,last,true) # initiate a small forward buffer

source = last

x1 = source.fluxsmootht(4)
x2 = source.removegrain(11,-1)
x22 = source.mt_makediff(mt_makediff(x2,x2.removegrain(20,-1))).MinMapBlur()
enhD = mt_lutxy(x22,x22.removegrain(4,-1).sbr(),"128 x y - abs 2 / 1 1.6 / ^ 2.51 * x y - x y - abs 0.1 + / * +",U=2,V=2)
enh = source.mt_adddiff(enhD,U=2,V=2)

tr = 4
sup1 = x1.removegrain(11).MSuper(hpad=8, vpad=8, pel=2, sharp=0)
sup2 = enh.MSuper(hpad=8, vpad=8, pel=2, levels=0, sharp=1)
multi_vec = MAnalyse (sup1, multi=true, delta=tr, blksize=8, overlap=4, truemotion=true, global=true, search=5, searchparam=8, dct=5, mt=false)
source.MDegrainN (sup2, multi_vec, tr, thSAD=220, thSCD1=400, thSCD2=116, thSAD2=120, limit=135)

FineDehalo(rx=2.4, ry=2.4, thmi=80, thma=128, thlimi=50, thlima=100, darkstr=0, brightstr=1.0, showmask=0, contra=0.0, excl=true)

LSFmod(ss_x=1.0,ss_y=1.0,strength=12)
mergeluma(removegrain(11,-1).removegrain(11,-1).removegrain(11,-1),0.11)
GradFun2DBmod(thr=1.8,thrC=2.1,mode=2,str=1.0,strC=0.0,temp=10,adapt=64)

Prefetch (SI_PhysicalCores ())

Oh, wow. How did you do that? It looks stunning.

Could you also post your x264 script, with the exact settings that you encoded this video? I would like to use it for my backups.

I simply used a script of great master Didee

In MDegrainN the main thing not to go too far in parameters thSAD and limit, not to make the image bald with wax persons, as on breadboard models of мadame Tussauds. I hint that at noise suppression there should be a sense of proportion.
Besides it I saw halo and applied FineDehalo.

Adjustments х264 the following: --crf 17.0 --preset slow --tune film --profile high --level 4.0 --ref 10 --aq-mode 2 --merange 32 --bframes 10 --trellis 2 --psy-rd 1.00:0.12 --threads 4 --qcomp 0.70 --partitions all --subme 11 --no-mbtree --keyint 240
