How to change the Camera's size?

[Mewious]

i am trying to make this

into this

I’ve tried using the Camera.ViewportSize but it’s not possible to edit it.

Is there any way to do this effect without using a ViewportFrame? I’m trying to avoid duplicating the entire game.

if any of you can help me that would be great!

You could try changing the FOV and adding frames around the sides

You could make the viewport smaller and then add frames around the sides.
