If a baseball was thrown in the air, two observers in different locations watching the ball would agree upon the arc of the trajectory that the ball traveled. What they would disagree upon is where that trajectory was and how long it lasted.
How about if we placed a camera to the ball?

Its perspective is completely different from both viewers.
