My Camera Pivot moved from its center or original place.

Guys! I need help. After taking 60 shots. Somehow my Camera pivot point shift from original pivot, now my every shots and animation is messed up. Can anyone tell me how to reset camera’s original pivot. Yes, I tried right click and reset pivot point but that didn’t work.

All I can do is assign new camera but that is not the way and extra work. I am talking only about Sequencer Editing. Not game. Thank You
