I skipped the batch process cause for the whole workflow I/we have to combine two functions with four variables:
1) Resize image: depending on two formats (1920x1080 / 1200x600) or "Longest side" (width or heigth = 4x options)
2) add Canvas Resize - depending on the formats (1920x1080 / 1200x600)
I think IF "Canvas Resize" would have as well the option "Longest side option" it might be done in one step.
What do you think?
Resize with option "Longest side"

Canvas Resize without option "Longest side"

And: I found the two "preset voodoo lines" of my changes in xnview.ini (via comparison before & after changes)
[ResizeDlg]
geometry=@ByteArray(\x1\xd9\xd0\xcb\0\x3\0\0\0\0\x2\x83\0\0\0\x66\0\0\x3}\0\0\x2\xcb\0\0\x2\ (...)

I can now add this lines in the AppData setup for everyone

Thx for the hint!
