Question: Creating pause at end zoom of Ken Burns slide show
I'm working on a slide show in iMovies 10.1.8 and am attempting to create a pause on the zoomed-in portion of a photo in Ken Burns. I read an old post (2005) that said that once you have made a duplicate Ken Burns frame (option - drag) you click on the "end" to highlight it and then option - click on the "start" to make them one, but that doesn't seem to work. I've created a duplicate photo with the same zoom parameters but would like to know how to preserve the exact zoomed-in portion of the photo to extend viewing time of the close up/zoom. (I've recently upgraded from iMovies 8.0.6, only because I was forced to do so and am ... struggling.) Any help would be appreciated. Thanks.
