NNEDI3 - rfactor settings

[gheppell]

I am converting some minidv footage to 4k and applying a number of filters.  

When I resize I set the hieght to 2160 and allow the width to be automatically calculated to 2880.  Further, I set the ouptut par to 1:1, understanding that the input PAR is 8:9.  In VS, I use the NNEID3 resizer and check GPU.  I have an intel arc380 graphics card.

I Bob deinterlace using QTGMC and apply some quality filters.  The output is as I want, but it is very slow to process (~2.11fps).  In providing the vs spring to AI (Gemini in my case), it notes that the way I am doing it is by grossing up the size by a factor of 8 (rfactor=8) only to downsize it immediately thereafter.  

Is there a way to adjust this in the Hybrid GUI.   Here is the script I generate.   Please do not hesitate to point out any other inefficiencies that you find in my script.  Thank you
