I apply the same settings on two slideshows,but the last one(on top track) doesn't show the fade-in fade-out effect, the first one displays the effect good, what happened?
Irene - Clips need to overlap for there to be a transition. In your bottom track the clips overlap (as arrowed) so there is a transition. But in your top track there doesn't appear to be any overlaps.
Thanks, Eric. The problem is, I did set overlapping time as 1 second in slideshow creator, but the result shows as the top track, no overlapping at all.
I don't know the answer. Slideshow Creator is not something I normally use as I do video. But playing around with it I have no problems achieving overlaps. I tried three slideshows. Is your Effect set as "Fades"?
Suggest you delete the problem ones. Save, then restart MS15 and try again.
