I have to admit, by this time almost forgot what GradFun3() is all about... but the "StackedVertical" got my attention, so, tried again, and new day, new luck!!!!

Rewrote the split to put the ORIGINAL smaller:

Code:

vid1 = LSmashVideoSource("Y:\test.MOV")
vid2 = vid1.GradFun3()
vid1 = vid1.ReduceBy2().Info()
Overlay(vid2, vid1, x=0, y=0, mode="blend", opacity=1)

and again, thanks for the StackVertical!!

So, it DOES work, but... no fat lady was singing

To be honest, without looking with a microscope, the two images look the same, so changed to

Code:

GradFun3(thr=1000)

there, clearly there is a huge difference, things are totally FUZZY on the bottom image... changed to "0" complained about having to be positive (so we know it works), then set to thr=0.01, but again, saw no noticeable difference..

anyways, Thanks for everyone's positive support and help... it was a journey, and now can mark checkbox been there, done that on GradFun3(), so I'm good until someone comes up with GradFun4()
