Closest parameters to equal johnmeyer's script?

I have been experimenting with MVTools and have used a trimmed down version of this script (https://forum.doom9.org/showthread.php? … ost1800439), namely no remove grain and dct=4, to render a movie at 2x framerate. It was a great success with no noticeable artifacts at all. (The movie was the blu-ray copy of Jesus Christ Superstar, 1971 version)

This took way too long though, and given that gpu-based calculations for motion vectors are essentially equal to cpu-based calculations, except way faster, is there a way to configure SVPflow2 params (or through the Manager GUI) to get equal or better results than the jm script?

Ideally I'm aiming for maximum smoothness and hoping that artifacts are not an issue. I can compare any suggestions with results from my avisynth script that I used for the movie render.

Thanks for any help!
