Degrain vs. Denoise ?! - shazzla - 10.04.2021 Hi! I would like to know ,what is the difference between degrain and denoise?! I did some search but no clean anwser was found. And can somebody give me an answer about what is a "generally good" degrain/denoise algorithm in Hybrid? I want to keep as many details as possible. I know its subjective ,because different movie/different algo... Thats why i said "generally good". Any reply appreciated! Thanks in advance! RE: Degrain vs. Denoise ?! - Selur - 10.04.2021 (Film-)Grain (read: https://en.wikipedia.org/wiki/Film_grain) is usually a light sort of noise. Where as noise is often stronger than grain and usually can have tons or reasons. Since filtering always destroys details/information there is no way to DeNoise or DeGrain without loosing some. If you want to gain some compressibility gains some degrain with RemoveGrain or SMDeGrain usually is a good way to not loose lots of details but get some boosted compressibility. If you really have artifacts you want to clean using a denoiser or degrainer there is nothing I would recommend. Different filters work differently and depending on the source might really destroy lots of information. Filtering is always about subjective preferences. -> I c/wouldn't recommend anything really.

It has nothing to do with Hybrid... you can try Neat Video if you have one of the host applications (https://www.neatvideo.com/features/compatibility). Great tool, good performance and not that expensive. RE: Degrain vs. Denoise ?! - shazzla - 08.07.2021 Greetings (again) ! I would like to know which is the heavier degrain filter? I did many test,bit the results are not so obvious... Imho the lightest is SMDG by default. Heavier is.... MLDG or Temporal Degrain? RE: Degrain vs. Denoise ?! - Selur - 08.07.2021 That all depends on the noise&co in the source. RE: Degrain vs. Denoise ?! - shazzla - 08.07.2021 Oh,i think i understand now.... Thanks ,Selur! |
