Temporal denoising doesn't work for me

Support Compositing and Post Processing

Hi all! So, I’ve tried to get into temporal denoising but the built in feature (the one in developer extras that you execute ) doesn’t seem to make a difference to my rendered frames? I’ve made sure to follow to preparatory steps: vector + albedo pass, developer extras, Optix denoiser, .exr render etc.

I’ts not like the tool doesn’t show up: it is right there in the search menu and when I initiate it blender freeze for a minute so clearly it does something, but for some reason it leaves the rendered image sequence identical to as before.

Could someone with more experience look into my scene and say if there is something missing and/or whether it works on your machine?

Have you verified that the images are perfectly pixel identical? Temporal denoising doesn’t magically solve a difficult render, it’s a subtle help. It’s possible that it is doing something, but it’s not enough.
