Filter Recommendation for noisy DVD source

[sundance]

I'm trying to pre-process a rather noisy, grainy DVD source with AviSynth to get better compression results with TMPEGenc.
Would anyone like to share his/her experience and filter parameters? I wonder which filter (or combination) (temporal/spatial/sshq or the denoiser in TMPEG) is working best for that job?

Thanks

generally these settings from Gordian Knot are good:

Especially no.1, you can also change it to TemporalSmoother(2) for a little more filtering. Also try these before and after resizing to see what is best for you.

# DENOISING: choose one combination (or none)
# 1) little noise (fast)
#TemporalSmoother(2,1)
#
# 2) medium noise (slow)
#SpatialSoftenMMX(1,4,6,false,false,4,4,6,8)
#TemporalSmoother(2)
#
# 3) heavy noise (very slow, you have been warned)
#SpatialSoftenMMX(2,4,6,false,false,4,4,6,8)
#TemporalSmoother(3)
#SpatialSoftenMMX(1,4,6,false,false,4,4,6,8)

second and third cases look stupid.

spatialsoftenmmx does already process some sort of temporal filtering.

and you have to define what noise you want ot remove, because with those "working good" gknot setups you will get a picture smeared in 99% cases.

http://web.syr.edu/~tjmyers/animefilters.html has a good demonstration of some noise filtering for anime, some of the principles and settings could be applied towards non-anime material. At least the different settings and screenshots can give you an idea of a starting point.
