I was making this script for a game I was making, basically it reduces any loaded humanoid animation to the FPS you want at runtime/makes them look retro, cause I see alot of animators animating retro anims just to get this look.

(Put it in StarterCharacterScripts)
This works on any humanoid-loaded animation btw.
(This was only tested on R6 so it only should be expected to work there)
