Yes, it does beat FF3DFilter! It also alters x264.exe encoding results as it gave me 41.8mb instead of 53.2mb without changing anything else, but it lost too much details in encoding. I'm trying again with higher encoding settings to compensate.
Question. For dual-graphics computer, to make sure it runs on the Radeon, if I'm running AVSMeter in a CMD shell, which application do I have to configure as "high performance", CMD or AVSMeter? |

First of all, you did not tell us what settings you used for the de-noisers. Secondly, you're comparing apples and oranges, the algorithms of these 2 are very different. The difference in size of your encodes just means that KNLMeans (with the settings you used which we don't know) removed more noise and therefore details. Using "higher encoding settings" will not bring back details lost with excessive de-noising. No idea what "configure as high performance" means. You select the device with the KNLMeans "device_type" parameter. You can test it by using the "info = true" parameter.

fft3dfilter(sigma=3, bt=5, bw=48, bh=48, ow=24, oh=24, sharpen=.15) with KNLMeansCL(D=2, A=1, h=3) Spatial has more impact on performance than Temporal, and I haven't seen much difference at all between D=2, A=1 and D=2, A=2 Quote:
Which means that when I preview the script, KNLMeansCL definitely has more details. By encoding with x264.exe (preset veryslow), however, there's something about KNLMeansCL's patterns that makes x264 discard much more data. So the preview has more detail while the final file has less details. I just have to play around to adapt the encoding quality setting to compensate for this. It's not an issue, but this is curious.

not true, denoisers got their own ways to distinguish noise and actual image, and some does it better, so you can kill a lot of noise and lose not that many details, some does it, well, not that good, you lose huge amount of actual image along with noise, extreme case, blurring filter, the origin of all modern denoise filters, will sacrifice the whole image to remove noise
I wouldn't use frequency domain denoisers (FFT3D and its superior DFTTest ) to do regular kind of denoise stuff, they make ringings like all frequency filters, and very destructive to high frequencies unless you don't filter high frequencies at all |

I did an encoding test on another video. This time the output file was slightly larger than when using FF3DFilter. So, it alters the way x264.exe decides what to keep, and sometimes it gives a small output, sometimes a larger output, depending on the source.
The biggest difference I'm seeing between FF3DFilter and KNLMeans is that with this, the image almost appears 3D. Even with a very low quality source, the shapes somehow take a 3D life. Whereas the source itself is just flat; and with any blurring denoiser it still lo9oks flat. |

And because this gets run first, all other operations afterwards start from better quality source and the difference gets amplified with NNEDI3 frame quadrupling. Another difference is that FF3DFilter needs sharpening afterwards, while this doesn't lose the sharpening to begin with.

To write a OpenCL program, a SDK in required, like CUDA Toolkit (Nvidia), APP SDK (AMD), INDE (Intel). For execute a OpenCL program is only required a device drivers. |

I see. Odd though that they have not provided a 1.2 SDK yet.
