Apply a Ken Burns effect to a slide

Some themes, such as Classic and Ken Burns, allow you to use a Ken Burns effect when displaying slides. The Ken Burns effect zooms in to or out of a photo while panning across its longest dimension. You can apply the Ken Burns effect to the entire slideshow or to individual slides. When you apply the effect to individual slides, you can also choose where the panning begins and ends.

If the faces in the photos have names assigned to them, the Ken Burns effect takes this information into account when cropping and positioning the faces in the slideshow.

Note: The Crop controls and Ken Burns effect are not available in all themes.
