You must select each still one at a time and apply the pan and zoom. You can select multiple slides, either adjacent or random and apply the effect to all of them at once. To select adjacent slides, click on the first in the sequence, hold down the shift key and click on the last one. All of the slides will be selected. To select random slides, hold down the control key and click on each slide you wish to select. Studio doesn't have a random function.
