Does anyone know how to edit the duration of photos in IMovie specific to the IPhone? I can't seem to find a way to edit the duration of my images so I can add audio to them and turn them into videos. Currently I'm using the editer on Windows 10, but I find the quality to be a bit subpar, I would like to use IMovie instead, but I can't figure out how to do it. Does anyone know any keyboard shortcuts, gestures, etc, that would allow me to do this?
