So small scripts possibly faster to post in text form. v3 is possibly equal to posted in https://forum.doom9.org/showthread.p...64#post1969764 .

Here you go:
Topaz Video Enhance AI v2.6.4 using Artemis Medium Quality v13 (Note: Medium Quality refers to the source material) Using my AMD Radeon RX 5700 GPU I get about 16 FPS on that type of video. And here is EZdenoise again, this time with TR8 and settings as before: I get about 90 FPS with my AMD Ryzen 3900X CPU. Pretty darn good for being over 5 times as fast, if you ask me.

Here my quick attempt with TemporalDegrain2; a KNLMeansCL post processing may be more appropriate than dfttest I used:
https://ibb.co/MDZBcFK Code:
TemporalDegrain2(degrainTR=8, postFFT=3, postsigma=6) Comparizon with Topaz VEAI: https://imgsli.com/MTEwNjE3; with given settings TD2 removes more noise but blurs the edges more; changing its setting, TD2 can perform better. Thanks takla for EZdenoise, for sure is competitive and is worth a try (for live action Topaz is not adequate)

" live action???"
In theory it can be tested with FFDSHOW +AVS script RAW processing. So with some in-out capture-playback card (or may be easier with newer IP-based live video streaming) it can process live. Or a set of capture card + some video output card. I plan someday the MDegrain-based cleaner can be installed before MPEG4 live broadcast encoder to help with output quality. For 'large tr' and overlap processing it may be hardware accelerated with a set of DX12-ME accelerators arranged same as typical 'mining rig'. Or may be just with fast enough multicore CPU. For live with low-delay it is required special mode of mvtools for 'backward search only'. So it can have about 1 frame delay only. But it will cause noise burst after scene change to about tr-number of frames. Or may be some 'intermediate asymetric search' mode with adjusted shift of forward and backward frames to balance between delay and noise burst at scene change. In theory with MDegrainX (1-6) it can be simulated now with simply collecting MVs from asymetric forward-backward MAnalyse params. MAnalyse need special new shift param to control frames request from MDegrainN in multi mode. Last edited by DTL; 2nd June 2022 at 11:05. |

Hello. Thanks for joining the conversation. And thanks for that website. I'll make use of it in the future.
It would have been great if you had also provided some benchmarks for time spent with each filter. The last time I tested other degrain filters TemporalDegrain2 was by far the best but also by far the slowest. Has this changed? And as you correctly pointed out, comparing spatial-temporal denoising vs just temporal, the result is to be expected, especially for anime, where you can use strong sigma without many drawbacks. |

Here is another comparison. This time from a real world video.
https://imgsli.com/MTEwNjM4 I can confirm, the denoising is just as effective in motion. Settings used: Code:
ConvertBits(16) EZdenoise(thSAD=200, TR=8, Chroma=true) ConvertBits(10, dither=1) |

The power of AviSynth! The only doubt I have is that I resized the topaz image from takla for the comparison on imgsli, but I see the artifacts on the original topaz image as well. P.S.: On the other hand the red stripes on the face are less "defined": a less aggressive denoise in TD2 is required anyhow.

Added ShowMe()
Can be used to more easily find a good thSAD value. (Look at the top left corner during preview with AvsPmod) (And make sure to ignore any value that is shown on frames right after a scene change) Should be placed right after your Source filter (except for when your video has black bars, in which case you need to crop them first) Example: Code:
LWLibavVideoSource("C:\Users\Admin\Documents\INPUT.mkv") Crop(0, 140, -0, -140) ShowMe() Last edited by takla; 1st July 2022 at 18:31. |

EZdenoise can also work as "DeRainbow" very effectively.
Comparison here Used with Code:
EZdenoise(Chroma=true, thSAD=0, thSADC=2000) Last edited by takla; 17th October 2022 at 16:06. |
