How do I remove the noisiness in my post process material?

I’m experiencing some noise in my post process material that I don’t want. You can see the effect here: Imgur: The magic of the Internet

It’s happening even when I’m not moving. Lumen is disabled. Reflections are disabled (but still render if I choose the reflections option in the show menu?).

Actually, you can see this noise even without a post processing material. What causes this? Imgur: The magic of the Internet

I had post processing material that pixelated things and was having weird noise/jitter. I was able to fix things for my project from the render settings by changing from TAA to FXAA along with a few other lighting/lumen related tweaks.

That might fix the jitter but it also might change the visuals in a way you’re not happy with.
