From another thread:
I've used it mainly on denoised renders from Blender and there it works.
But apparently there are denoising functions in DR too, see here, but I have not tried those yet.
I'm using the super scale property in the clip's attributes (2x, low, low), also retiming to 50% with highest settings.
Probably it's just too much noise.I'm on an iMac pro with a Vega 64 and just finished a 20 second Falcon video rendering that took about 2.5 days to complete at 1080p, 60 fps and 64 samples (still very noisy).
I have been experimenting with DaVinci Resolve lately and it looks promising.
There is a "super scale" functionality and it works quite well, same with the "optical flow" retiming.
I tried DaVinci Resolve 15 on my Video to upscale from 1080p to 4k with noise reduction.
What settings are you using? It doesn't look significantly better here. Perhaps, there's just too much noise?
