You’ll obviously have to change the points where to zoom, but your code should end up looking something like this:
&zoom on # # to % in # (this is the part for zooming in)
&zoom on # # to % in # then zoom on # # to % in # then zoom on # # to % in # then zoom on # # to % in # (this is the camera shake)
To make it look better, you may need to repeat the code a second or third time. Hope this helped.
