To increase the length of a still image in iMovie is quite easy but has to be done in a specific order. Even that part is easy.
1. Make sure that you are NOT using any Ken Burns effect on the still image. Uncheck the KB Box
2. Do the info thing and change the duration.
3. Put the required Ken Burns effect back in. Check the KB Box
The reason you cannot change it any other way is because iMovie worked out the movement on the image (the Ken Burns effect) based on the original, default, length of the still and it will not allow a change because that would spoil the KB effect.
Hope this helps
try it an let us know
I created an iMovie with many still photos. For some reason I was unable to change the duration of the photos except by manipulating the transitions. When I would double-click on the photo in the timeline, or choose 'get info', it would not allow me to change the duration.
Has anyone else experienced this? Do you have a fix for it?
