Denoiser / Noise Reduction in Resove

Because the ursa mini 4k ISO 800 its still unusuable in the low light i must to denoise the pictures in DaVinci Resolve. But if i push spatial NR luma more that 10, the pictures have a plastick look. How you denoise a movie in Da Vinci Resove but preserve the cinematic look? Can tell me your secret step by step?

real men don't use denoise.

find the comfortable setting you can tolerate, then set it to half of that value and add just a tiny tiny grain back.

"filmic" look has grain.

Neat video plugins is probably the better option.

Are you using v12.5 as the NR is much better.

Temporal NR will often give you better results than Spatial, particularly if you have to push it hard.

Yes Peter, I use Resove 12.5 Studio. Its a realy emprovement, but not enough for ursa mini 4K isues with FPN and flickering...I am thinking if the magic solution from Blackmagic is to emprove the DaVinci Resolve denoiser or to fix the sensor 4K isues with a new firmware...What you say?

Help me please! Can somebody tell me why DaVinci Studio 12.5 show me the movie with extra many noise that in reality? When i play the movie with quick time, vlc, media playe,r the movie have just little noise. In Premiere CC 2015 the movie its like in reality with very little noise. Just in DaVinci the movie have very much noise. What its wrong with my DaVinci 12.5? This issues its annoying because i can't make a right denoise in this condition.

Do you have a proper monitor?
Yo can't judge the picture on the computer screen!

I use a UHD Dell professional monitor. But it is not relevant for my problem beacause i use the same monitor and PC when i play from quick time, vlc, media player or Premiere 2015 CC. So, another idea?

Don't use a Dell display. Use a calibrated display optimized for Rec709, particularly one with no added enhancement, showing you true 10-bit (or better) performance. If you don't do that, you'll have no real idea what you're dealing with; an uncalibrated computer display could be exaggerating real problems, or they could be covering up serious issues. What you want is for the monitor to tell you the truth. A Dell monitor is not going to do this.

Thanks Marc for your advise. But i dont understand yet how its possible the same monitor to show me the movie without noise when i use Premiere CC 2015, Quick time player, VLC player, Windows Media player and with noise just when i use DaVinci Resolve 12.5. You dont think that its a wrong settings or another problem with my DaVinci? An uncalibrate monitor can exaggerating the colour... but to introduce noise? Supose my Dell monitor is uncalibrate, then why dont affect all programs and not just DaVinci?

Noise can always be exaggerated in bad monitors. If the monitor is not calibrated, you have no idea what you're looking at.

I have also seen cases where the monitor covered up noise, so we didn't really know there was a problem until much later on in the post process. So that can happen, too.

Marc, i understand your point of view. But you dont answer me at my question: why just DaVinci Resolve see this noise and all programs that i have used dont see this noise? Why in DaVinci Resolve when i stoped the movie its not noise pictures and when i played the movie its noise?

Can you post a link to a short clip of the problem footage? Then we may be able to help.

Could the issue be that your Resolve Gamma settings are lifting the blacks, as compared to the media players you listed, and consequently you are seeing more noise?

Check out your settings at: Project Settings > Color Management > Color Management Settings > Timeline Color Space.

You have right! I has posted 2 pictures make it with printscreen function. One is when i play the movie and i have noise and another its when i still the movie and dont have noise. Whats wrong with my settings?

Check your debayer settings. My guess is you are in optimize for playback mode, so it changes between stop and play mode. Use the highest quality setting always.
