Hi. I’m rendering a 1080p test image and was wondering if the denoiser is working as it should. My render time is 21 seconds and the denoiser time is 34 seconds. The denoiser is set to Corona high quality. I want to render an 4K animation but the denoise times seems quite long. Is it better to turn off denoiser and just do the denoising in post in say Davinci?
Have you tried Intel denoiser? I don’t use Corona Denoiser anymore, I don’t see any advantages over Intel’s.
This one should be faster and give you (in my opinion) better results.
No I’ve not tried that one as I thought it was best to use Corona high quality denoiser for animation.
Thanks, I’ll give the Intel denoiser a go. 
I used Intel Denoiser also for animations. But make a test, it can result in some flickering. In that case, render some more passes and do some extra work in Fusion.
If you don’t know, just follow this tutorial here:
Hope that helps!
