Compare filters after encode?

[Mr. Monte]

Not sure if this is the right place. However, I am trying to find an application/GUI that will allow me to apply x264 presets and/or Avisynth filters and then do a comparison to see the before and after.

IOW, I have a 1:30 movie I ripped from a DVD to my hard drive. It is an older movie (1980's-90's). I would like to encode say 30 seconds to 1 minute at various CRF's and apply various filters to see the affects...comparing them side by side with the original if possible.

TIA :thanks:

Interleave(a,b)

interleave is awesome, as is stackhorizontal and stackvertical.

# If Videos start at different frames
frameadjust=0

# Videos to compare: (v1 is original, v2 is encoded or whatever)
v1 = AviSource("original.avi",false).trim(frameadjust,0)
v2 = AviSource("encoded.avi",false)
sub = v1.subtract(v2)
substrong = sub.levels(122,1,132,0,255)

return StackVertical(StackHorizontal(v1.subtitle("original"),v2.subtitle("encoded")),StackHorizontal(sub.subtitle("Difference"),substrong.subtitle("Difference amplified")))


Or, if you're lazy like me, and can't be bothered copy pasting all that every time, you can convert it into a function.

function Difference(clip v1, clip v2, string "name1", string "name2")
{
name1 = default(name1,"clip 1")
name2 = default(name2,"clip 2")
sub = v1.subtract(v2)
substrong = sub.levels(122,1,132,0,255)
return StackVertical(StackHorizontal(v1.subtitle(name1),v2.subtitle(name2)),StackHorizontal(sub.subtitle("Difference"),substrong.subtitle("Difference amplified")))
}
