I am sorry, this is because these are not the same frames (frame number from the beginning).
Now I write this script:
FFVideoSource("D:\Kiki.mkv")
a=SincResize(1280,720,taps=1)
b=SincResize(1280,720,taps=20)
Overlay(a,b,mode="Subtract")
Kiki.mkv is BDRemux 1920x1080
Result - Oh My God, absolutely black rectangle!
So, the taps parameter is ignored. It's terrible!
But no, I'm mistaken! Taps aren't ignored!
Next I tried this:
FFVideoSource("D:\Kiki.mkv")
a=SincResize(640,360,taps=1)
b=SincResize(640,360,taps=20)
Overlay(a,b,mode="Subtract")
And now I see something. A few white curves and stars.
Does it mean that the difference between taps=1 and taps=20 is very, very little and is practically visible only if resize ratio is very, very big?
But where are giant ringing artefacts which must be produced by taps=20? I don't understand this...
