I changed the default in Options/Preferences 1.13 seconds. When I apply the transitions to the entire project it uses the default of .7 seconds. I am having to go to each transition and change it to 1.13 seconds! I have over 200 slides, How can this be done in bulk?
The problem with that is that it changes the duration of the images and the duration of the transitions together proportionally. That may not be what you want to do.
