denoising dv camera captures

i would like some example scripts how to denoise and cleanup/sharpen this filmed interview with not much light and the noise the camera produces because of that

i am using this now

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\LeakKernelDeint.dll")#take it from here: http://leak.no-ip.org/AviSynth/LeakKernelDeint/
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\FluxSmooth.dll")
Load_Stdcall_Plugin("C:\Program Files\AviSynth 2.5\plugins\yadif.dll")
Import("C:\Program Files\AviSynth 2.5\plugins\Seesaw.avs")

AviSource("H:\week 05.AVI")
#DirectShowSource("E:\week 04\voof bff")

AssumeBFF()  #or AssumeBFF if necessary


a = last
b=a.degrainmedian(mode=2).VagueDenoiser(threshold=0.8, method=1, nsteps=6, chromaT=0.8)
SeeSaw(a,b, NRlimit=6, NRlimit2=7, Sstr=2.5, Slimit=5, Spower=5, Sdamplo=6, Szp=16)

Tweak(bright=-10, cont=1.2)
results ar eok, but i have no idea if this is correct

There is no correct way. And quality is always something personal.

Most important in the first image is to correct the colours (I hardly believe this was shot with a DV camcorder).

I would let the second as it is - the colours looks on my PC LCD monitor quite good, there's extremely low low-light noise for the area of interest, and denoising it would kill the details, you have too much "on-screen faces" - the people would look unnaturally.

Degrainmedian and seesaw are both pretty strong!

I'd suggest trying fft3dfilter / fft3dgpu with low sigma values.

If you have time, MDegrain2 will rock your socks off
