digitalFAQ.com Forum - Need help with my vapoursynth script for upscaling.

As a follow-up on my capturing thread ( https://www.digitalfaq.com/forum/vid...sharper-2.html ), I'm now in the post-processing/restoring phase, using vapoursynth

Below my current script. It does the following:

1. crop noise&black borders existing in capture
2. correct the broken u,v channels at the right edge coming from the D8 camcorder during PAL Hi8 playback, different pixel width for each in my case
3. deinterlace with QTGMC
4. resizing with spline64
5. upscaling with nnedi3cl

I think I'm doing something wrong in the upscaling steps.
Disabling/enabling the nnedi3cl does give the result.
I'm resizing with spline64 because the nnedi3cl has no w/h parameters.
Should I try using nnedi3_rpow2 instead ?

Code:
