Explanation of different effects?

[Obsidinho6]

Many of the effect options are pretty obvious, but there's a bunch where I don't understand what they do, and when playing with the sliders, nothing seems to really change. For example: "Scanline phase shift." Nothing seems to happen when I play with this option. "input luma filter" is another. Also what does the "random seed" option do? Would it be possible to get some sort of written explanation of what each option does, especially for those of us who don't quite understand some of the jargon? Or if there is an explanation out there, can someone point me in the right direction?

The Input Luma Filter is used to reduce the rainbow artifacts.

For example here is how the frame might looks like without the luma filter. You can see in the frequency section (the black-white vertical line one), there is a block of "rainbow"

And here is the frame with the luma filter on with box mode. You can see that the block of "rainbow"
is gone in the middle

For the random seed one, it is used for generating the patterns of noises like luma noises or edge spikes.
