According to me there is not too much grains on the screen...it is looking clean to my eyes..But Maybe It can have some invisible noise.

so try 'Deen' First on the source...then Use LimitedSharpen To sharpen it...

Now see the below image :

See At The edges of the Boy's face & the invisible noise also got removed... :)

& here is the script which i have used.


Deen("w3d",4,7,9)
LimitedSharpen(strength=100,Smode=4,special=false,dest_x=1016,dest_y=720)



Try it & Best of luck

Should i sharpen before or after degraining? Why does the filtered pic. look brighter?

You must degrain the source before sharpening it..

the filter pic looked brighter because i have changed the colour specs to Yv12 because deen supports yv12 inputs unfortunately. :p

Deen is destroying the detail.

Deen is destroying the detail.
Absolutely...Deen is only a denoiser..its not a motion-compensated denoiser.

any sort of normal denoiser can wipe out a fair amount of detail..that is why denoise 1st & then add additional Sharpeners & grains over the video..

Like after doing denoising..

Add

LimitedSharpen().addgrain(0.12)

or

MSharpen().grainfactory()

I will test this source with temporal-degrain and let you know.
