I edit this script can run to 144fps
Just change the "num=" to target fps

I have a problem
When I use mvtools the video out will decreased to nv12(8bit)
How can I edit to keep 10bit output
thanks

worked, but i want to ask, when using this, my CPU works harder than VGA, how do to make the VGA work optimally and minimize the load on CPU? btw, my VGA is Nvidia RTX. It should be possible, right, with the increasingly advanced technology now?

I could never get this script working right, so I just kept using SVP3 (last free version).
If anyone wants to give it a shot, this is made mainly for 3D movies but it can still be used as a regular player: https://github.com/ThreeDeeJay/PotPlayer3D/releases/latest

Worked for me like a charm. Win11, Nvidia GPU. Managed to lerp 24 fps to 120 fps. Looks awesome on my 120 hz TV)
I used the original script, but had to tweak some parameters in the script to keep performance stable. Because if fps gets unstable - audio quickly gets out of sync with video.

First tweak was to set more memory. I'm not sure if I really used that much, but doesn't hurt for sure.
SetMemoryMax(4096)

Second tweak was suggested by captain-k4. It's much better than hardcode amount of CPUs
Prefetch(#CPUS)

Overall I'm very happy that I've discovered that topic. This is super useful. Thanks.
