Well, the filtering was created in 5 minutes..
The software is truely great, instead of just applying "generic" noice 
reduction, you first build noise profile, by taking "noise samples" from 
the picture.
JohnV(11:21 AM) :
Then you do the filtering using the profile.
ChristianHJW(11:22 AM) :
Hmmm ... sounds interesting. I sent a message to matroska-devel about 
it, so the guys know
JohnV(11:22 AM) :
here are some more examples:

The girl was mine though, and because of the demo, i had to save it 
again as jpeg, so it's not ideal. Anyway, the noise redcution is highly 
configurable also.
ChristianHJW(11:23 AM) :
Looking forward to get this as an avisynth script .. lol

JohnV(11:24 AM) :
It's not very fast... because it really is quite advanced despite of the 
name.. :B
JohnV(11:25 AM) :
anyway, I was reading usened and web, and many reviews, and everywhere 
this software came up..
JohnV(11:26 AM) :
If you test the demo, read this step-by-step guide. It gives you very 
quickly an idea how it works.
JohnV(11:28 AM) :
you first select a larger area for "rough noise analyzer". Then you 
select smaller areas to fine tune the noise equalizer.
It creates the profile according to these samples. Then you can save the 
profile, or tweak it in many ways, and of course apply after you have 
previewed and happy.
