Thank you both for the fast advice!
Will try 0.6.11 as suggested by Groucho! Fred.

My opinion of the filter is quite varied: on some material it performs brilliantly, clearly doing a better job than MDegrain2. This is especially true for "blotchy noise" that results from brightening really dark video. However, on other material, despite several people's claims that it doesn't destroy details, it absolutely ruined the video. This wasn't minor, but was really bad. The problems were most apparent on things like water glasses on a banquet table, where the subtle shadings on the glass disappeared. On another video, the wavy folds on a dress shirt also disappeared. So, take a hard look at any contoured surfaces that have no "high frequency" detail and instead simply have subtle changes in shading. The filter is also dog slow without any GPU assist, and MT doesn't seem to do much (several people have said in this thread that MT and GPU end up working at odds, although without a GPU, I would think MT could still do something, but what do I know). For me, any filter that cannot get above 1 fps is a unusable. I simply don't have multiple days to devote to any individual film or video. Life is full of "engineering trade-offs," and performance does matter. Last edited by johnmeyer; 24th May 2019 at 20:21. Reason: change "about" to "above" |

Hi!
I recently find knlmeanscl and it works pretty great but I have some questions: Why do I get glitches at the start of the video sometimes? And how should I get rid of them? Here's an example: https://mega.nz/#F!mUpyTIII!IXp43ePL1PETUGyVMYNUUg (source and encode are both ~1min long) Code:
DirectShowSource("D:\raccoons\DVD1\VIDEO_TS\VTS_01_1.VOB") QTGMC(Preset="Fast") SelectOdd() Crop(14,2,-16,-0) FillMargins(1,0,1,1) bbmod(0,2,4,6) knlmeanscl(D=2, A=3, h=3, device_type="GPU") DeHalo_Alpha(rx=2.0, ry=2.0, darkstr=0.4, brightstr=1, lowsens=50, highsens=50, ss=1.5) GradFun3(thr=0.35, radius=12, elast=3, mask=2, mode=0, smode=0, debug=0, lsb=False, lsb_in=False, staticnoise=False, y=3, u=3, v=3) Spline36ResizeMod(688,538,1,0,-1,-1) Thanks in advance, pcroland. |

If that doesn't solve the glitch problem, test each of the filters/functions separately. Yes, get a decent card (GTX1060/70/80).

Earlier versions of the nVidia driver had a relevant MPEG2 bug. Maybe when you installed the 1050 you upgraded to the new driver, which has been fixed.
Still, there shouldn't be any problem with DGIndex. I'll have a look with your stream. Last edited by videoh; 25th November 2017 at 23:43. |

I know there's a terrible fieldblend, the glitches that I was talking about: in the encode.mkv file you can see frames flipping upside-down randomly in the first 5 sec. But now it's fixed, thanks for the help. |

it was a while since I used knlmeanscl but I believe last time I tried it, it was pushing somewhere around 25 fps, and that was on a computer that is now five years old (i5-3570k, gtx... 670? I think?)
you can be in the next decade right now if you want to, is what I'm sayin' |

If you're getting < 5fps you're either using unreasonable settings or you should consider updating your hardware. Otherwise just forget about GPU filters. By the way - Intel integrated graphics are utterly useless for OpenCL.

Code:
SetFilterMTMode("DEFAULT_MT_MODE", 2) AVISource("BadToonSample.avi") ConvertToYV16(interlaced=true) orig=last ev=orig.assumetff().separatefields().selecteven() od=orig.assumetff().separatefields().selectodd() ev ue_chroma = UToY(ev).blur(0,1.5).binomialblur(5).ttempsmooth(maxr=6,lthresh=150, strength=6).KNLMeansCL(d=3, \ a=8, h=6, device_type = "GPU", device_id = 1, channels="Y") ve_chroma = VToY(ev).blur(0,1.5).binomialblur(5).ttempsmooth(maxr=6,lthresh=150, strength=6).KNLMeansCL(d=3, \ a=8, h=6, device_type = "GPU", device_id = 1, channels="Y") YToUV(ue_chroma, ve_chroma) MergeLuma(ev) ev_filtered=last od uo_chroma = UToY(od).blur(0,1.5).binomialblur(5).ttempsmooth(maxr=6,lthresh=150, strength=6).KNLMeansCL(d=3, \ a=8, h=6, device_type = "GPU", device_id = 1, channels="Y") vo_chroma = VToY(od).blur(0,1.5).binomialblur(5).ttempsmooth(maxr=6,lthresh=150, strength=6).KNLMeansCL(d=3, \ a=8, h=6, device_type = "GPU", device_id = 1, channels="Y") YToUV(uo_chroma, vo_chroma) MergeLuma(od) od_filtered=last interleave(ev_filtered,od_filtered) assumefieldbased().assumetff().weave() Prefetch(6) It's an ugly nth gen video with horrible chroma errors. I wrote a script that will suffice, with about 10fps, but the above is better -- but only in quality, not speed. The 1-hour video would take 165+ hours to process, which is not reasonable. Quote:
I can borrow a card, but I don't think it's going to give a usable performance boost. This is just a slow filter, GPU or not. Feel free to test the above script, share your fps results. Can anything replace KNLmeansCL for the sake of speed?

Hardly surprising with 4 calls to the filter and d=3, a=8. Even a GTX1080 would struggle.
Not to mention that you're running it in 6 threads which just consumes GPU memory and probably slows it down even further.
