How to make this zoom effect

[Dejan24589384y7at]

Hi guys, can someone please tell me how this effect/overlay or I don't know what it is - is created? Looks good and simple, but I don't have a clue how is made.

It's not really a zoom effect, rather the same image scaled up and cropped: It is called picture in picture.
