i post my avisynth script that align two clips low and high exposer




a=ImageSource("I:\tw2\N\tiff\image%d.tiff",start=1,end=28988,fps=5).ConvertToYV12() #Low exposure clip

b=ImageSource("I:\tw2\E\tiff\image%d.tiff",start=1,end=28988,fps=5).ConvertToYV12() #High exposure clip



c = Interleave(a, b)     # here it merge the low and high exposure to even and odd frames



a_cont=9.214285  #adjust this for Low exposure

b_cont=0.08         #adjust this for High exposure



a_ref = a.NonlinUSM(1.2,2.6,6.0,8.5).HighlightLimiter(1,true,1,true,100).tweak(cont=a_cont).GaussianBlur(VarY=1).MT_binarize(threshold=80).greyscale().invert() #adjust this for Low exposure if needed MT_binarize(threshold=25) and this NonlinUSM(50.2,2.6,6.0,8.5)

b_ref = b.NonlinUSM(50.2,2.6,6.0,8.5).HighlightLimiter(1,true,1,true,100).tweak(cont=b_cont).GaussianBlur(VarY=1).MT_binarize(threshold=25).greyscale().invert() #adjust this for High exposure if needed MT_binarize(threshold=25) and this NonlinUSM(50.2,2.6,6.0,8.5)



#return StackHorizontal(a_ref ,b_ref )   #Enable this only to see that Low and high exposure looks about the same and to do the adjusting to the settings when all looks ok put back this symbol # before return



c_ref = Interleave(a_ref, b_ref)



# calculate stabilization data

mdata = DePanEstimate(c_ref,trust=0.01,dxmax=32,dymax=100)



# stabilize

c_stab = DePanInterleave(c, data=mdata)



#Now the low and high exposure are align and now it separate low and high exposure frames



b2_stab = c_stab.SelectEvery(6, 2)  #Here is the high exposure clip

a2_stab = c_stab.SelectEvery(6, 1)  #Here is the Low exposure clip



#i now input a2_stab and b2_stab to my HDR script and it does the hdr thing and output a merge singel clip :)



you need this functions to
 


function HighlightLimiter(clip v, float "gblur", bool "gradient", int "threshold", bool "twopass", int "amount", bool "softlimit", int "method")

{

#SetMTMode(5) enable this if you use MT

gradient = default (gradient,true) #True uses the gaussian blur to such an extent so as to create an effect similar to a gradient mask being applied to every area that exceeds our threshold.

gblur = (gradient==true) ? default (gblur,100) : default (gblur,5.0) #The strength of the gaussian blur to apply.

threshold = default (threshold,150) #The lower the value, the more sensitive the filter will be.

twopass = default (twopass,false) #Two passes means the area in question gets darkened twice.

amount = default (amount,10) #The amount of brightness to be reduced, only applied to method=2

softlimit = default (softlimit,false) #If softlimit is true, then the values around the edges where the pixel value differences occur, will be averaged.

method = default (method, 1) #Method 1 is multiply, the classic HDR-way. Any other method set triggers a brightness/gamma approach.



amount = (amount>0) ? -amount : amount



darken=v.Tweak(sat=0).mt_lut("x "+string(threshold)+" < 0 x ?")

blurred= (gradient==true) ? darken.gaussianblur(gblur).gaussianblur(gblur+100).gaussianblur(gblur+200) : darken.gaussianblur(gblur)

fuzziness_mask=blurred.mt_edge(mode="prewitt", Y=3, U=2, V=2).mt_expand(mode="both", Y=3, U=2, V=2)

multiply = (method==1) ? mt_lut(v,"x x * 255 /") : v.Tweak(bright=amount)

multiply = (method==1) ? eval("""(twopass==true) ? mt_lutxy(multiply,v,"x y * 255 /") : multiply""") : eval("""(twopass==true) ? multiply.SmoothLevels(gamma=0.9,smode=2) : multiply""")



merged=mt_merge(v,multiply,blurred)

SetMTMode(2)

fuzzy= (softlimit==true) ? mt_merge(merged,mt_lutxy(v,merged,"x y + 2 /"),fuzziness_mask) : merged

return fuzzy

}



and this to
 


function NonlinUSM(clip o, float "z", float "pow", float "str", float "rad", float "ldmp")

{

z   = default(z,   6.0)  # zero point

pow = default(pow, 1.6)  # power

str = default(str, 1.0)  # strength

rad = default(rad, 9.0)  # radius for "gauss"

ldmp= default(ldmp, 0.001) # damping for verysmall differences



g = o.bicubicresize(round(o.width()/rad/4)*4,round(o.height()/rad/4)*4).bicubicresize(o.width(),o.height(),1,0)



mt_lutxy(o,g,"x x y - abs "+string(z)+" / 1 "+string(pow)+" / ^ "+string(z)+" * "+string(str)+

 \                        " * x y - 2 ^ x y - 2 ^ "+string(ldmp)+" + / * x y - x y - abs 0.001 + / * +",U=2,V=2)



return(last)

}

Hi Mattias, I sent you a pm yesterday, don't know if you watch your message box, so I'll delete this post  if it becomes useless.
