Degrain vs. Denoise ?!
#1
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!

(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.

Just for your information. 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.
