I realize there are already similar posts to this one, but so far as I could tell, most of them involve (& focus on) transitions, whereas my issue is strictly with setting the duration for which a photo is held in iMovie.
Effectively, I am trying to get a 'stop motion' feel from iMovie. I deselected the auto-apply 'Ken Burns' to all photo imports in the project preferences and figured I would edit the photo duration afterwards, given that the shortest possible duration in the project preferences is 1s, which is much too long. That is where I run into trouble: the "duration" field is acting up a great deal - sometimes it won't even respond to my entering different numbers, other times it will. Sometimes when it does respond to my typing numbers, it won't let me type anything in the decimal position. When it does let me type something in the decimal position, e.g. 0.2s, when I hit enter, it re-sets the time to 2.0s. I've tried different formats for entering time (0:00:2; 0:00:02; 0,2; with & w/out 's' etc) - all to no avail.
I'm very curious to know if anyone else has reported this problem, & if so what the solution is.
In case anyone else is having this problem, I did find a workaround:
1. Import your photos as necessary
2. Select one photo and manually crop to desired time scale (e.g. 0.3s)
3. "Trim to selection"
4. Select that same clip & bring up the window for editing the duration, check the "apply to all stills" box.
5. voila - amazingly this works.
Although this is a perfectly easy workaround, I'm a little disconcerted by the fact that iMovie won't repond properly & would be very interested to understand why.
Thank you in advance for your help.
