Post Processing tips

Ok, so I’m at the point where I’ve rendered a bunch of image sequences in cycles and I’m now trying to make them look a little prettier before chopping up into a video. So far I’ve taken to creating de-noised sequences using ‘d-noise’ then overlaying them with the original render using opacity, playing with saturation/brightness/contrast (all in the VSE) and voila.

As I’m just groping my way through, I’m sure there is a better workflow to spruce up images post render and would appreciate any tips from those more experienced users.

Any tips?
