How do you denoise data?
The simplest algorithm for denoising time-series data is taking a summary statistic using a rolling window. A rolling window collects observations into groups of n size. The groups are shifted one observation at a time, creating a “window” that passes over the dataset, hence the name.

How are denoise-denoising options in latest nightly builds?
In latest 2.91 nightlies, I see in the Scene settings under Denoising, a Render option with choices NLM and OpenImageDenoise. How are these related? Are they the same? If I keep my denoise node in the compositor and turn on the Scene-settings denoise do I get two denoise passes?
What’s the best way to use denoise node?
For Cycles, it is recommended to use the Denoising Normal render pass, which is available when enabling the Denoising Data passes. Optional albedo render pass to better preserve detail. For Cycles, it is recommended to use the Denoising Albedo render pass, which is available when enabling the Denoising Data passes.
Which is better compositor denoise or openimagedenoise?
The short answer is that if you enable the Denoising in the render options you do not need to use the compositor Denoise node. And OpenImageDenoise is better. The longer answer is that OpenImageDenoise is the same as the compositor node but it works while rendering rather then after the the render which can speed things up a lot.
What do you use the denoise passes for?
They are not meant to be recombined or used for anything else then for the feature as you can see explained in the devtalk forums by Brecht Van Lommel: It’s intended for the upcoming feature of animation denoising, where denoising happens in a post processing pass ones all the frames have been rendered.
