Why is my render ghosting?

While rendering the whole sequence, it does this


and it does this

One of the samples is dragging at the end (idk if its normal or not). And yes, i tried it with motion blur on and off. And i used “Lookat” function in camera. (if its may causing these artifacts pls tell me;D)

I already watched the tutorial to disable “Lock at display runtime” Did 16 temp 2 spatial samples and its still ghosting. I had a another previous project and it did it as well.
Should i just inrease the temproral samples or is there another solution?
