Can anyone make a tutorial how we use the new SVPcode with premiere?

Any reason in particular that you need to use Premiere Pro? You can use special plugins to export to avisynth/vapoursynth scripts, which you then feed to a video encoder, but that's a deep rabbit hole to do down.

SVPcode is a stand-alone utility. Whatever you have in Premiere, you can just export it then use that video file with SVPcode.

it doesn't work this way
not every "plugin" can be used in Premiere just because it's called "plugin"

Please tell me how to export AviSynth/AviSynth+ scripts. I bought SVP 4 and am trying to encode some anime to x265 60fps but the last generated scripts found in the scripts folder in app data always gives me the error saying that "there is no function named ffdshow_source" ... Sorry if this is off topic. But you mentioned there are plugins for this. I could really use some help. I've been searching for the solution for weeks

I attached an image of the settings Id like to encode the video with and here is the script SVP produces. Would it be possible to use one of those plugins you spoke of to  make a template that I can maybe use in an encoder such as StaxRip, MeGUI, or Internet Friendly Media Encoder (IFME)

Just as a side note scripts that were generated back when I used SVP 3 worked fine in MeGui. SVP 4's gives the error I mentioned

# This script was generated by SVP 4 Manager.
# Check https://www.svp-team.com for more details.
