Updated version of Catmull-rom Cinematic Camera

Hello everyone!
I was searching a garry’s mod addon to make smooth movement with cameras, when I found Catmull-Rom Cinematic Cameras. I was happy because it was exactly what I was looking for , but one in-game , I saw that it was out-dated.
Could someone please update this addon ? It would help me out alot.
I can’t post all the errors i’m getting in the console in here since there’s so many D:

Thanks in advance.

Still searching. All I could find is “Moving Camera V1.5” , it does quite the same thing but that’s not really what I want.
