Quote:Thank you for looking into this. Just FYI, I tried auto-adjusting height and setting width to 2880 and also no auto-adjust just entering both 2880 and 2160 but rfactor remained at 8.No surprise, this has nothing to do with auto-adjust
(Which should always be used! If you are not using it you are probably making a mistake or you are trying to avoid adjusting the PAR for some unknown reason.)
=> I uploaded a new dev which has "Filtering->Vapoursynth->Misc->Script->Adjust PAR before resize" as a new option, which when enabled in your case will create something like:
# resizing 720x480 to 720x540 to adjust for PAR before resizing
clip = core.fmtc.resample(clip, w=720, h=540, kernel="spline64", interlaced=False, interlacedd=False) # before YUV420P8 after YUV420P16
# resizing using NNEDI3CL
# current: 720x540 target: 2880x2160 -> pow: 4
clip = edi_rpow2.nnedi3cl_rpow2(clip, rfactor=4, nsize=2, nns=2) # 2880x2160Cu Selur
Ps.: I also added a code-block in your initial post and also adjusted the title.
