How do I set the duration of a keynote presentation so that it loops for say one minute and then ends
I am trying to save a keynote presentation as a quicktime video. I cannot find the wya to set the time so that the presentation loops until the time is up and then ends. The presentation is only two slides in a loop. I would like this to run for 60 seconds and then end when I convert it to a QuickTime video. Any help appreciated.
