NLmeans effect on detail
Posted: Mon Jun 29, 2020 6:10 pm
I know the stronger the denoising settings, the more detail is filtered out, but if something doesnt compress as well as i want, i would rather denoise than reduce RF/bitrate.
I did some testing with the luke cage season 1 bluray, as the marvel netflix shows are know for being overly noisy, probably cos its artifical. Without denoising, it was like 95% the original size, so not even worth compressing, but with NLmeans ultralight preset film tune, it was about 45%. Much more reasonable, and much closed to the 35% average i got with other tests ive ran on the custom preset i use.
I ask this question cos the image wasnt noticably different to the encode without the denoiser. Not just in terms of detail, but also the noise itself, yet it had a very positive effect on bitrate.
So if this is the case, is it safe to leave it on? Nlmeans ultralight film? As i dont want to have to test everything i encode to see how it would benefit, especially as other stuff i have encoded didnt compress so well either, but were much better with nlmeans even tho they werent particularly noisy in the first place.
