In anticipation of noise reduction I stopped all 3D projects. I switched to web design. In my scenes there is a lot of work for noise reduction

The firefly removal of the denoiser can work pretty well, but only until too many samples have picked up the same "firefly" (which is technically no longer a firefly in this case, just an unconverged caustic).
edit: However, it seems to kill the glossy reflections. Strange.

Can a denoiser handle the channels of light groups?

Yes, but it would need to be run on each lightgroup imagepipeline separately, so it would take a lot more time than if we only denoise the "main imagepipeline".

OK. This is really needed option. Without it, the compositing is not possible.
I propose to make such a check

I'm starting a series of 200 renders of LED strips. With noise reduction of all channels, I need to perform 50 renderings, and a bit of compositing. Without noise reduction of all channels, I need to perform all 200 renderings.

A 10 mins rendering, it makes animations possible.

Try to increase the "Histogram distance threshold" parameter, the result should be smoother.
