Best way to handle this kind of noise? - Bartoloni - 10.06.2025 here a sample: https://www.wcn.it/noise.avi i tried various denoise filters but i would be sure what is the best to use, on the final part of the clip there is a dark wall with a lot of noise. RE: Best way to handle this kind of noise? - Selur - 10.06.2025 Will look at it after work and report back. RE: Best way to handle this kind of noise? - Selur - 10.06.2025 After loading the source and checking the preview, the next thing I did was looking at the source with separate fields: I added: clip = core.std.SeparateFields(clip, tff=True) clipEven = clip[::2] clipOdd = clip[1::2] clip = core.std.StackVertical([clipEven, clipOdd]) into a custom section (and checked that the scan type was progressive). This showed there were tons of duplicates and blends and I couldn't really see a pattern. With enough motivation, one could probably find a pattern which would allow fixing this, or go through all the frames and replace unwanted ones with interpolations. So I removed the custom part, and overwrote the scan type to tff and used QTGMC without Bob. Then I cropped the source and applied Retinex (that helps with the general brightness): # color adjustment using Retinex clip = core.retinex.MSRCP(input=clip, sigma=[25,80,250], fulls=False, fulld=False) followed by AutoWhite and started playing around. (https://pastebin.com/n1sX9BWr) About the noise, aside from throwing some heavy hitters like: SpotLess, RemoveDirtMC, MCTermpoalDenoise, there's not much you can do aside from heavy smoothing and maybe throw some machine learning stuff at it. The general workflow for something like this should probably be: a. fix/replace fields/frames b. crop c. color and edge correction d. denoise Cu Selur
