Anyway, it's a prefilter so it doesn't need to be perfect, I guess it depends on source master level, simply use the value that saturates the bit range.

That's odd. The range is 1-2000 I think, and a regular rather bright movie like Green Book was pitch black with 100..

EDIT: Oh, a pointer regarding GradFun3plus, I think the default threshold for PQ sources should be higher. The default value is a bit too low, I'd go maybe for 0.75 or something like that.

I was still using neo_f3kdb_r6 version. Tried out _r7 and no problems with colour deviations so far.

But if that doesn't work, I'll try out Dogways mod of Gradfun.

Hi ked,

I have a very belated question about this gpuid "switch" in SMDegrain..

It has been bought to my attention that with the changes Dogway did to this function a few builds ago, that if it's left to default, any SMDegrain filter will use the GPU for filtering / pre-filtering.

Would that be the case ???

Do I need to change it to gpuid=-1 for CPU instead, for my scripts ??

Cheers

You need use gpuid=-1 for CPU. If not, Smdegrain will choose GPU is default

Thankyou for that, I will need to change all my script's then

And another question, with KNLMeansCL as a pre-filter, how do you change that to use the CPU, in SMDegrain....it looks like it's written a little differently to BM3D "instruction's".

Cheers

Anyway, I have to apologize to you. It seems neo_f3kdb() is the root of evil here and not SMDegrain. I totall forgot I usually add this later as the final filter to my scripts.

Was quite happy with its results and speed but I guess it's time to look for another debanding filter.

EDIT:



Well I chose DGDenoise() as it's an animation movie. Would it be beneficial to use BM3d instead?

HI LeXXuz,

i use a lot neo_f3kdb() and you mentioned that this is the root cause for color "changing". Do you know what would be the best alternative for neo_f3kdb?

this is my basic command for this filter:
neo_f3kdb(preset="veryhigh/nograin", dynamic_grain=false, output_depth=10)

Could you share yours for alternative?

I was still using r6 version of neo_f3kdb().

With version r7 I could not reproduce this problem so far:

Dogway I noticed some faint distortions in my encodes, barely noticeable.
So I played around with the preview mode a little and saw a lot of erroneous frames of the prefiltered clip. See pics below:



EDIT: I turned off DGDenoise and the errors are gone. Tried with no prefilter (-1) and BM3DCUDA (6) with no errors.

Btw. about "speed, memory and quality" shown on the right with different colours. Are they displayed anywhere? All I see is the gamma curve in the preview.

[Dogway]

LeXXuz, I cannot reproduce your issue. I used your settings over a 2.40 ratio 1080p source at 16-bit.

What did you change between this and this? Result looks fine but no settings changed?

The legend is when you define show="speed" in string format so you can have some hint where to tweak for optimization.

Weird. I changed nothing, just stepped a frame forward in MeGUIs preview window and took a new screenshot. Some frames look fine, others have these strange colour distortions.

I did a few encodes with DGDenoise() just alone to see if these errors occur, but no. Have latest nVidia Studio drivers installed for RTX 2060. I will check this very same script on another machine with a RTX 3060TI once that's free as it's currently occupied by running a longer encoding job.

EDIT: That is actually not true. It does also happen with DGDenoise() alone.

[Dogway]

Just upload a small sample and your script so I can test here.

Is the source interlaced? (a possible point of failure)

No it's 1920x800 @23p.

hi LeXXuz,

could you please tell me what is the application used by you to show SMDegrain results? Is this application shows in real time results of denoise without encode?

No. That is just the Avisynth preview window of MeGUI:

I'm not sure what you are after, but maybe WaveForm_FilmStrip() will fit the bill.



Here in WaveForm thread:- https://forum.doom9.org/showthread.p...05#post1965005

Here client script with SHOWAUDIO=False [where it dont need Waveform plugin]

# Import(".\Waveform_FilmStrip.avsi")
#AviSource("D:\G.avi")
Colorbars.Trim(0,-100)

WINDOW    = 3           # Frames Wide = 2 * WINDOW + 1
HEIGHT    = 0.33        # Audio graphs height, 0.333 = 1/3 of result filmstrip image height.
UNDER     = false       # True, then audio graphs stacked under video, else overlay over video.
ZOOM      = 1.0         # Amplify audio signal for viewing (1.0=No Amp).
SUBSIZE   = 0.5         # Suggest 0.0(off) to about 0.5. (0.0 <= SubSize <= 1.0) : 0.0 = No Frame Number,  1.0=biggest size for current clip Height (probably too big).
SHOWAUDIO = False        # Default True. If False, Switches OFF WaveForm Display, Shows FilmStrip Only.
W         = 264         # Default -1, (or 0 or +ve). -1 = Normal Downscale behaviour, filmstrip width ~= input clip width.
#H         = Undefined  # Undefined, Let W govern height of thumbnail images (or just dont use h=H in function call, same as h=Undefined).

###### Can Remove this lot ######
TONE      = False       # Replace Colorbars tone with selected TONETYPE tone
TONETYPE  ="NOISE"      # Pick from:- "Silence", "Sine", "Noise", "Square", "Triangle" or "Sawtooth"
TONECHANS = 5           # Tone Channels Count (test channels display)
#
(TONE)    ? AudioDub(Tone(Length=FrameCount/FrameRate,Type=TONETYPE,Channels=TONECHANS))  : Last
###### End Of Can Remove   ######
WaveForm_FilmStrip(window=WINDOW,Height=HEIGHT,under=UNDER,zoom=ZOOM,subSize=SUBSIZE,ShowAudio=SHOWAUDIO,w=W) #,h=H)
Return Last

EDIT: The Waveform_FilmStrip() script at linked post is the most recent version.

EDIT: If Waveform_FilmStrip.avsi aint in plugins, then need to import it.

EDIT: And here with SHOWAUDIO=TRUE [but animated gif(via VDub2 export) dont have audio, so silent]


EDIT: If required, you could eg Interleave(Clip_A, Clip_B) and use result with WaveForm_FilmStrip, even frames would be Clip_A, odd Clip_B,
or just use eg StackHorizontal(Clip_A,Clip_B) to view side by side.

Using SMDegrain and I'm having issues with random corruption artifacts. It happens randomly and I can't seem to find a fix.

SMDegrain(prefilter=5, str=0.8, refinemotion=true)

Any fix? Running AVS+ 2.7.2 and using the latest SMDegrain script. This doesn't occur in the source, and I have been using TempDegrain2 in the meantime with no issue, but it's painfully slow.

[Dogway]

AVS+ 3.7.2?
Update a small sample and full script since I'm not getting that issue.
Try with prefilter=-1 to see if it's ex_KNLMeansCL() related. Check dependencies as well.

Yeah, typo :P

Here's the sample.

AVISource("G:\virtualdub\tape transfers\sampledegrain.avi", true, pixel_type="YUY2")
assumetff().converttoyuv422(matrix="rec601", interlaced=true).convertbits(10)
tweak(bright=-9, cont=1.04, hue=-10.0, sat=1.12, coring=false, dither=true).convertbits(8)
Trim(58, 554)
qtgmcp()
#ChromaShiftSP(X=-.85, Y=-.25)
ConvertToYv16(matrix="rec601",interlaced=false)
MergeChroma(aWarpSharp2(depth=20,threads=4))MergeChroma(aWarpSharp2(depth=10,threads=4))
santiag(strv=0, nns=4, nsize=5, threads=4)
#converttoyuy2(matrix="rec601", interlaced=false)
SMDegrain(prefilter=-1, str=0.8)

I also tried simply

AVISource("G:\virtualdub\tape transfers\sampledegrain.avi", true, pixel_type="YUY2")
assumetff().converttoyuv422(matrix="rec601", interlaced=true).convertbits(10)
tweak(bright=-9, cont=1.04, hue=-10.0, sat=1.12, coring=false, dither=true).convertbits(8)
Trim(58, 554)
qtgmcp()
SMDegrain(prefilter=-1, str=0.8)

The issue was still there, although the result is different. Looks like it depends on both the source and what's behind smdegrain. Might not show up for you at all yet it shows up for me.

I did take out the tweak and convertbits lines, looks like the issue doesn't happen there, but I need those lines.

Same result.
