How to limit denoising on high motion areas?

[feisty2]

SMDegrain is definitely my favorite denoiser :)
it doesn't only remove grains but removes mosquito noise too and makes no artifacts :D
it works perfectly on low motion areas,but causes serious detail loss on high motion areas.
I want to know how to solve the issue (limit denoising on high motion areas)
here's a frame

after denoising, the man's hair looks very blurry (lower tr or lower theSAD won't help much but leaves some mosquito noise unprocessed)
smdegrain (tr=6,plane=0,Chroma=false,pel=4,subpixel=3,blksize=4,thSAD=400,Search=5,contrasharp=false,lsb=true,prefilter=3,thSCD1=200,thSCD2=100)

and I also tried MMask to limit high motion areas,but it doesn't help much, the man's hair still looks blurry

mask=a.MMask(backvec)
b=a.smdegrain (tr=6,plane=0,Chroma=false,pel=4,subpixel=3,blksize=4,thSAD=400,Search=5,contrasharp=false,lsb=true,prefilter=3,thSCD1=200,thSCD2=100)

I guess MMask is the right way to solve the problem, maybe I used it in a wrong way :(
here's a short sample I trimmed by mmg from the original dvd

Thanks in advance for any help :stupid:

I just re-read the instruction of mvtools2 and tried 3 parameters and found (kind=1,ml=10,gamma=2.0) will solve the problem
but I still don't know how things get worked... the official tutorial is too professional to me
I'd like to know if there's a easier MVTools2 tutorial for new learners :)
