How to zoom in on part of a scene

So I have a scene where one character walks over to another, and I want the camera to zoom in on both of them. How would I do that? How can you zoom in/out of an object or scene without actually increasing the size?

:confused:

encapsule them both and add a scale layer. Itā€™s good practise to always keep a top scene paste layer with everything inside it.

Thanks Rylleman, that worked.

Also thanks to Genete. Iā€™ll check out that camera widget at some point, but right now since Iā€™m new Iā€™d like to keep things as simple as possible, so Iā€™ll go with the scale layer solution.

is there any way to zoom out or in of a scene gradually, instead of at once?

also, when zooming in at once using the scale layer, how would you then zoom out?

To scale gradually just animate the amount parameterā€¦
To zoom out, make the amount parameter of the Scale layer negative.
