It is just an idea, currently I cannot test (my computer is temp disabled).
nf=YDifferenceToNext()
This is the kern of the Motion adaptive script. So the idea is to use this value to tweak some settings in HybridFupp.
Any suggestions?

Lol.
In fact you don't have any idea at all just a question

HybridPP is somehow already motion adaptative so there won't a lot of space for more tweaking. In the threshold used perhaps. But that won't be very efficient.

Anyway, I should try.
BTW, can you say me which is my question?

Actually I guess that your last line can be called "question" as it ends with a question mark

Ah, this one. Heh, well, I can't say I am the most experienced Avisynth scripter... But the idea is an idea...

MA "recognises" motion by Y/Luma differencies,
HybridFupp does this by motionmask, so that are two diff. approaches and would get in conflict.

I got that integration of NF/YDifference-Idea in the time when QMF was out as it only got fixed values/routines which do kick in at a touched threshold. But no matter you still recognised these KickIns.

In fact I really meant the thresholds... Hmm let HybridFupp do the work...

Me do the work, guys !
