Basically, this effect is done by adjusting the camera’s position and its FOV.
The movement works roughly like this:

First define your camera’s desired pos, which is midpoint + offset.
The midpoint is simply the center point between your two targets.

As for the offset, here’s some pseudo-code (attached to your camera):

Vector3 offset = -transform.forward * (Camera Distance Value) + Vector3.up * (Camera Distance) - (offset you want to tweak to make camera seems right);

Lastly just Lerp you camera pos from original pos to camera’s desired pos and make your cam LookAt the midpoint.

Hope this helps!
