Restore old vhs

[algia]

Hi all,
I'm trying restore old vhs and this is the code I used

clip="C:\Users\alojal\Desktop\sample disk\ZIA ROSA\ZIAROSA-IN\zia rosa.mov"
video=FFMpegSource2(clip, atrack=-1).Crop(240,18,-240,-18).ConvertToYV12(interlaced=true)
FFMpegSource2(clip, atrack=-1)
Crop(24,18,-24,-18)
AssumeBFF()
QTGMC(preset="slow",FpsDivisor=2,ChromaMotion=false,border=true,ChromaNoise=true,DenoiseMC=true,NoiseDeint="Generate",StabilizeNoise=true,GrainRestore=0.0,Sharpness=2)
RemoveDirt(limit=10,_grey=false)
ConvertToRGB(matrix="Rec601", interlaced=false)
GamMac(LockChan=1,LockVal=130,RedMul=1,GrnMul=1,BluMul=0.9,Show=false,Verbosity=2,hith=0.5,loth=0.5,th=1,scale=2)
ConvertToYV12(interlaced=false)
FFT3DFilter(sigma=8, beta=1.0, plane=4, bw=16, bh=16, ow=8, oh=8, bt=3, kratio=3.0, sharpen=1.0, scutoff=0.3, svr=1.0, smin=4.0, smax=30.0, measure=true, interlaced=false, wintype=0, degrid=1.0, dehalo=1.0, hr=2.0, ht=50.0)
ChromaShiftSP(2,4)
DeHalo_Alpha(rx=2.0, ry=2.0, darkstr=1.0, brightstr=1.0, lowsens=50, highsens=50, ss=1.5)
LSFmod(defaults="slow", strength=39, kernel=12, preblur="OFF", secure=false, Szrp=2, Spwr=4, SdmpLo=4, SdmpHi=48, overshoot=1, undershoot=1, overshoot2=2, undershoot2=2, soothe=true, keep=20, edgemode=0, show=False, screenW=720, screenH=576)

StackHorizontal(video,last)
return last

after GamMac I see light blu haloing around the hair and in the wall
I would like, more shapness and some suggestion
thank you in advance
