Adding a deadzone to a specialized camera

I’m trying to make a very smooth platformer camera. The camera is on a spline, and follows the player around. The Vinterp ensures that the camera moves ahead of the player so that we can see what’s ahead of the character. The blueprint works great, but because it’s always trying to look ahead of the character, the camera is pretty much always moving. I’d like to add a deadzone so that it will sit still, but can’t figure out how to do it. The built in camera lag doesn’t really help, it just dampens the motion a bit. What should I change to make this happen?
