In my opinion, it's pretty pointless to use super resolution without doing a proper degraining first (and a proper RE-graining afterwards). SR only works really well in restoring detail on very clean material, as soon as grain is there, all you'll do is enhance the micro-contrast of the grains themselves. Also, that needs to be done on a scene by scene basis. Neat Video or Dark Energy Anti-Matter come to mind for the degraining. And THEN do a comparison. Don't be discouraged by the lack of detail on the degrained images, once you introduce the grain BACK into the footage, it will seem a lot sharper and more detailed. My experience with SR is that it does work well with VERY "un-shaky" sources, however, I think the median with regular, reverse and nnedi3+sharpen sounds genius to me, I gotta try this myself.
