iMovie photo clip duration won't increase
Making my eighth movie with iMovie 10.3.10. Haven't had this problem before. The photos I'm adding to the timeline won't increase in duration. Some are limited to less than 1.0 sec. and can't be increased by moving the yellow border around them. If I delete and then import the same photo a second time, it will first appear as if the duration is longer but will quickly drop to an undesirably slow duration. Transitions, even though I import them at 1.0 sec, will also shorten their duration by themselves. I can manipulate video clips without a problem. Thanks for your help.
