Help with correctlyt upscaling with Real-ESRGAN.

[Selur]

When I toggle on Upscale then select Real_ESRGAN and the x2Plus model and leave the resizer box on the default Spline option, if I go back to the Resize option I see that has been turned on by Hybrid, I’ll turn it off then run job.

Under 'Crop/Resize->Base->Resize->Picture resize' you enable whether resizing should take place what the resize resolution should be.
Under Filtering->Vapoursynth->Frame->Resize you can overwrite the 'Crop/Resize->Base->Resize->Picture resize->Resize method'.
=>
a. if 'Crop/Resize->Base->Resize' is disabled, 'Filtering->Vapoursynth->Frame->Resize' has no effect
b. the resolution after resizing the one selected under 'Crop/Resize->Base->Resize->Picture resize'
After applying RealESRGAN&co, Hybrid will adjust the resolution to the value under 'Crop/Resize->Base->Resize->Picture resize'.
Best look at the generated script using the Vapoursynth Script View if you are unsure what is happening.
