I think i will make some presets like convolution3d.
It definitely seems that the Brislawn 2 function gives the best results. At least it was on my own tests, both on an anime (GITS) and and a movie (Brotherhood of the wolves)

Speed isn't so bad after all, with 6 nsteps on a 640x256 movie, it's ~20 fps on my p4 2.4GHz

So here are my findings:

For a high quality movie:

Code:

VagueDenoiser(threshold=0.75,wavelet=7,method=1,nsteps=6)

Threshold can be increased up to 1/1.25, even 2 but you may lose fine details, it's visible a little on skins for example.

For a high quality anime:

Code:

VagueDenoiser(threshold=2,wavelet=7,method=1,nsteps=6)

Some may find 2 a little too strong.

On these movies, i've put VagueDenoiser before resizing, if you put it after, you may need to decrease the threshold.

Now i'll seek bad quality movies/anime and try to enhance them
