source
src=last

SMDegrain()
den=last

ex_ContraSharpening(src) # or LSFplus in contra mode

ex_makeadddiff(last,den,src)

Well this way I get a picture that is almost as noisy as the original but with the grain being static now. I already noticed the missing last argument in the first version of your post and corrected that.

I could post screenshots, but to spare me the hassle with an image provider, I'll just post SAD values from mvtools. Hope you'll take my word for it.

untouched: 26455
denoised: 7720
denoised with internal contrasharp: 8477
denoised with external cs and makediff: 25965

mvtools script:

super = MSuper(mt=false, pel=2)
forward_vec1 = MAnalyse(super, isb = false, delta = 1, search=3, chroma=true, mt=false)
MShow(super,forward_vec1, showsad=true)

(In case someone wonders about those numbers, they are in 16bit´. You have to divide those by 256 if you want a relation to those numbers you use with SMDegrain.)

Idk, maybe it is intended that way. But the denoised areas should still be clean which they are not and those numbers reflect that obviously.

[Dogway]

Maybe the principle was ill-founded, try to do an ex_makediff between src and denoised -with LFR- (grain extract) then add that to the sharpened-denoised clip

ex_makeadddiff(den,src,last)

I have that error when you SMDegrain

SMDegrain(6, 400, prefilter=5, ContraSharp=true, RefineMotion=true, plane=4, limits=false, DCTFlicker=false)

Thanks! Just fixed. I forgot to update the new Super global variable that I changed in SMDegrain to align to QTGMC+

Hi Dogway, I tried QTGMCp but can't fix the interlaced video of some scenes, can you help me how to fix that??

Frame 920

AssumeTFF()
QTGMCp(Preset="Medium", Sharpness=0).SelectEven()

Sample:

resize to 1920x540, then upscale back to 1920x1080

[Dogway]

The moiree effect is present even in the fields so you might need to target the issue locally as postprocessing I think.

Can you have any suggestions script for that??

resize after or before Deinterlaced??

I tried and got better results but I still have errors

propSet("_FieldBased",0)
deep_resize(1920,540,grain=0)
deep_resize(1920,1080,grain=0)
AssumeTFF()
QTGMCp(Preset="Medium", Sharpness=0).SelectEven()

[kedautinh12]

After updated QTGMC+ to latest ver with moiree option, I tried but still doesn't work

AssumeTFF()
QTGMCp(Preset="Medium", moiree=true, Sharpness=0).SelectEven()

I did have an additional look the sources:
a. seems like DVD resolution at best, so you could probably downscaling to dvd resolution without loosing detail.
b. Dogway is right, this isn't caused by deinterlacing and won't be fixed by it, this would require some specific local processing like copying parts of a previous frame/field over to the broken ones
=> probably not worth the effort this would require

a, i try downscaling to DVD but errors won't gone

[kedautinh12]

Ok, I tried other Deinterlaced scripts and work very well. Some scenes have ALIASING after Deinterlaced. Therefore, I fixed it with ANTI-ALIASING

AssumeTFF()
AnimeIVTC(mode=1)
daa3mod()

@Dogway: do you have any recommended method for stabilizing luma changes for a more accurate scene change detection with ffmpeg? I tend to get quite a lot of false detections just because the brightness between frames seems to change a bit (Withnail and I from the early 80s, rather LQ Blu-ray). If I raise the detection threshold, it starts missing too many scene changes to be useful. I'm not looking to catch all of them so I have some wiggling room. I've tried downscaling, severe blurring and using ex_luma_rebuild but no real help there.

[Dogway]

If it's some kind of luma flicker try ex_autolevels() (example)

Otherwise yes, you have to temporal blend the frames, except those for scene changes, so a catch-22 situation.

It depends if you want surgeon denoising, or a simple temporal blend, in such case replace the denoise with a TemporalSoften().
With SceneStats you can work on a scene basis, also it inherits SC weight from the source frame type.

Here are some examples:

https://forum.doom9.org/showthread.p...07#post1969107 (I recommend putting SMDegrain/TemporalSoften outside ScriptClip)

Thank you very much for the work done. I'm getting an nmod error. For what reason and how to solve?

Up image to another sever or you will waiting for mod approval forever
