Looking for BeforeDiff function

[thescrapyard]

I'm trying different split screen side-by-side comparisons and settled on the functions I found beforeafter and beforeline suit my needs better than a simple stackhorizontal(clip1,clip2)

There was also another function called beforediff that displays what was changed to see exactly whats happening if doing line darkening or more extreme filtering but the AMVWiki.org has been down for years and all links I found point to that as the source for the functions, or the one below that is also unavailable


Does anybody have the original BeforeDiff functions so I can add it to the original

This was the original topic I started hunting from, but this website is coming back as unavailable or may not exist:

For those that are interested, here is what I eventually tracked down and put in one script. beforeafter was easy to find but beforeline I found in another topic while hunting for all 3 functions

Thanks

# BeforeAfter by Absolute Destiny and Corran #
# e.g. #
# beforeafter(clip, placement, filters) or #
# #
# beforeafterline(clip, placement,filters) for a lined split #
# #
# 1 for vertical splitscreen, 0 for horizontal splitscreen #
# #
# Does not work on filters that use strings like deen("a3d",1) #

function beforeafter(clip a, int "placement", string "filters"){

placement = default(placement, 1)

Assert((float(width(a))/16)==round(width(a)/16), "Source image width must be a multiple of 16")

b=Eval("a."+filters)
c = (placement==1) ? stackhorizontal(a.crop(0,0,-((ceil(float(width(a))/32))*16),0).subtitle("before"),b.crop(((floor(float(width(a))/32))*16),0,0,0).subtitle("after")) :Stackvertical(a.crop(0,0,0,-height(a)/2).subtitle("Before"),b.crop(0,height(a)/2,0,0).subtitle("After"))

return c
}


function beforeafterline(clip a, int "placement", string "filters"){

placement = default(placement, 1)

Assert((float(width(a))/16)==round(width(a)/16), "Source image width must be a multiple of 16")

b=Eval("a."+filters)
c = (placement==1) ? stackhorizontal(a.crop(0,0,-((ceil(float(width(a))/32))*16),0).subtitle("before"),b.crop(((floor(float(width(a))/32))*16),0,0,0).subtitle("after")) :Stackvertical(a.crop(0,0,0,-height(a)/2).subtitle("Before"),b.crop(0,height(a)/2,0,0).subtitle("After"))
line = (placement!=1) ? blankclip(a,color=$FFFFFF).crop(0,0,(width(a)),4) : blankclip(a,color=$FFFFFF).crop(0,0,4,(height(a)))
d = (placement==1) ? overlay(c,line,x=width(a)-((ceil(float(width(a))/32))*16)-2) : overlay(c,line,y=height(a)-((floor(float(height(a))/32))*16)-2)

return d
}


As mentioned in the script that it won't work with filters that uses strings, it DOES work with all filters that use strings as I found that suggested in another topic. Just add """ to calling the function call and it will work without any issues

Example :

beforeline(clip,1,"""deen("a3d",1)""")
