Sorry, my comments were a little harsh, and not very constructive. The clip actually shows some promise.
Well, You_Too gave you a good suggestion on sharpening. LimitedSharpen is nice in some conditions as well. Just don't over-do it. Doing nothing is always better than doing something with artifacts.
As for the denoiser, IF I had to choose one, I'd use either TemporalDegrain or a variant of it like MCTemporalDenoise.
