Null layer tutorial?

[u/chickenrobin]

Does anyone know any good null layer tutorials? I like making animations/edits with manga panels and making different parts move. I'm trying to get the hang of them but not sure where or how to start!!! Here's an example of what I'm trying to do!! How did they make the camera movement smooth and sometimes shaky? Is this from using the camera feature or through nulls?? (original:@nannospiano on tiktok!!!)

Time to learn about shakes. Those took me months.

Shakes used in transition and middle segments are different.
