Great write-up @UHD thank you for the details. Appreciate it and I will look at the links in detail later today.
I noticed with the current version with MPV there are still some artifact issues that I hope can be handled better in the future.
For example, within the film Tenet, around the 35 minute mark the texture on the clothes has bad artifacting.
Tried to capture it here, link will be up for 24 Hours only. Source is 4K Bluray Remux of the film:

Also, after the 11th minute mark there are artifacts on the antennas at the back of the boat as it travels on water:

Not sure if versions above have fixed such issues, but it would be nice to have improved artifact masking.
Really appreciate RIFE, it is by far the best motion interpolation method I have seen thus far.

EDIT:
I backed up, then replaced the ones you linked with the ones inside (C:\Program Files (x86)\SVP 4\rife\models\rife), but it did not work. I will wait for the update via the app.
