Subset of timed photos
1. I have 170 photos in a slideshow. I have a global time of 2.5 sec except for 53 that I would like to make 1.7 sec. Do I have to set each of the 53 slides individually or can I set them all at once while not distrubing the remaining slides' timing?
2. When I play back my slide show it hangs up after about 45 photos. I have a MacBook Pro running OS 10.8.4 with a 2.2 GHz and i7 processor and 8 GB of ram. Should it being doing this? Is there a better way to preview my slideshow before I export it?
MacBook Pro, OS X Mountain Lion (10.8.2)
