What % are you guys finding works enough for your projects before using the denoiser?

I'll add pictures soon, but it looks like we can get away with rendering to ~5% noise and using .6 on the denoise for our 720p animations.

You just shared my personal defaults :)

Good Luck

Never underestimate the power of a well placed level one spell.

5% is the limit if you have not strong DOF or MBlur. Otherwise, you need  < 2%, I think.

Anyway, for indoor architectural animation, a value between 2%-5% is good enough =)
Denoise? 0.75 is the limit, in my animation test.
For still, better 0.5/ 0-6

yeah, I agree cecofuli, I think we might aim for 4% since we can afford to, the render times are about 30% of 1.3 with 5% noise, so a bit more time is definitely ok.
Here's the resulting 5% noise test

When you're sharing those denoise numbers, are you talking about denoise radius or denoise blending?

I must admit i'm rarely touch denoise radius too, although it helps to find better balance between  noisy and too plastic looking image. Let's hope that someday we'll get denoising that is fully adjustable after rendering. If i'm not mistaken, it was said that it could be delivered in 1.5 already.

I use following:

8-10% for quick previews combined with denoising
5% for finals that I plan to denoise
3% for finals that I don't plan to denoise

@ Rawalanche

do you use the same values for interiors and exteriors?

I didn't have the chance to test it extensively for interiors but for exteriors, I had to turn it off. Had a fine bump map on the building that needed to be "noisy", and denoiser made a mess on the grass.
Anyone else had similar exterior experience?

I love denoiser so much (thanx corona!!),
I always use 4% with denoise blend 0.6
Denoise radius is 0.6 too, because I experienced that with 1.0 it hurts my tiny leather bump texture a little bit. but I don't know is it still happening in 1.4 or not.

What is the relationship between radius and resolution ? Would use guys still use smaller than 1 radius for high-res renders ? Would there be any possible drawback (splotching?) ?

I have no idea about that, but imho it is related. I think I wont use smaller than 1 for denoiser radius for more than 4k renders. but I never get any project with more than 4k render.

When you guys say 5%, are you talking about a setting of .05 in the Noise Level Limit under the pass limit? And then say .6 for Denoise Amount and 1.0 for Radius?
