How to make the camera follow 4 players at all times, zooming in and out, along with some extra screen space padding on all 4 sides, so that they arent always sitting on the edge ?

From the logic I could make out that some sort of rectangle would be required, which would find the upper most, left most, right most and bottom most character and have the camera focus on the half way point of them all. Am I wrong in assuming so ?
