I make a denoise with MDegrain3 and after it I want to remove scratches using the vectors just calculated, like this: Code: ``` super = MSuper(source, hpad=32, vpad=32,pel=2) bks = 8 ov = 4 bvec3 = MAnalyse(super, isb=true, blksize=bks, delta=3, overlap=ov) bvec2 = MAnalyse(super, isb=true, blksize=bks, delta=2, overlap=ov) bvec = MAnalyse(super, isb=true, blksize=bks, delta=1, overlap=ov) fvec = MAnalyse(super, isb=false, blksize=bks, delta=1, overlap=ov) fvec2 = MAnalyse(super, isb=false, blksize=bks, delta=2, overlap=ov) fvec3 = MAnalyse(super, isb=false, blksize=bks, delta=3, overlap=ov) clp = source.MDegrain3(super,bvec,fvec,bvec2,fvec2,bvec3,fvec3,thSAD=400) # HERE, after Mdegrain3 should Msuper be remaked? super = MSuper(clp, hpad=32, vpad=32,pel=2) backw = MCompensate(clp, super, bvec) forw = MCompensate(clp, super, fvec) backw2 = MCompensate(clp, super, bvec2) forw2 = MCompensate(clp, super, fvec2) backw3 = MCompensate(clp, super, bvec3) forw3 = MCompensate(clp, super, fvec3) #removeDirt: _grey = false limit =30 clipa = interleave(backw3, backw2, backw, clp, forw, forw2, forw3) clipb1 = RemoveDirtJ(clipa,limit, _grey) V1 = SelectEvery(clipb1, 7, 3)``` Should I redo Msuper just after the Mdegrain3, before Mcompensate? As the vectors are the same from Manalyse, but the clip is the one denoised.

As to whether you should insert this step at all, perhaps compare with and without. In that case you might as well compare results with a second MSuper() instead. Cheers, Francois

Code: ``` super = MSuper(source, hpad=32, vpad=32,pel=2) bks = 8 ov = 4 bvec3 = MAnalyse(super, isb=true, blksize=bks, delta=3, overlap=ov) bvec2 = MAnalyse(super, isb=true, blksize=bks, delta=2, overlap=ov) bvec = MAnalyse(super, isb=true, blksize=bks, delta=1, overlap=ov) fvec = MAnalyse(super, isb=false, blksize=bks, delta=1, overlap=ov) fvec2 = MAnalyse(super, isb=false, blksize=bks, delta=2, overlap=ov) fvec3 = MAnalyse(super, isb=false, blksize=bks, delta=3, overlap=ov) clp = source.MDegrain3(super,bvec,fvec,bvec2,fvec2,bvec3,fvec3,thSAD=400) # HERE, after Mdegrain3 should Msuper be remaked? # Yes it should: super2= MSuper(clp, hpad=32, vpad=32,pel=2) backw = MCompensate(clp, super2, bvec) forw = MCompensate(clp, super2, fvec) backw2 = MCompensate(clp, super2, bvec2) forw2 = MCompensate(clp, super2, fvec2) backw3 = MCompensate(clp, super2, bvec3) forw3 = MCompensate(clp, super2, fvec3)```
 28th June 2014, 19:55 #4  |  Link franketto Registered User   Join Date: May 2014 Posts: 74 Thank you. Now I 'll do the extra MSuper. But I tried also without and the result seems good anyway. It's not easy to see well the difference, because it's removing scratches and in fact it removes them but probably the edges aren't perfect because it refers to the clip before Mdegrain3.
