High Quality 3D Denoiser Filter

[Gvaz]

I have some questions about this and google seems unable to give me the results I'm looking for.

I'm trying to watch a video with a h264 codec, and I'm trying to denoise the file up a little bit upon viewing. (also trying to figure out how to make all h264 video use the graphics card for rendering but that's something else)

I don't understand what the options mean in the settings for it, and what levels I should put it at.

What is "spatial luma strength", "spatial chroma strength", "temporal luma strength", and "temporal chroma strength"?

What level should I put this on to eliminate film grain while viewing? I'm thinking as a post-processing level of modification instead of editing the actual video file.

Hello, ten years later and I have this exact question. Don't suppose you had any luck in the past decade?
