I'm not interested in "live photos" like flowing water or a burning flame in an otherwise still photograph.
The kind of photographs I'm interested in is like "a person moves his/her head a little or winks (like 1/3 second), and then remains in a final position" - it ends just like a normal still photograph, no matter how long you look at it. The effect appears only for a short while flipping to a next shot.
How is this kind of effect called? How do I create and view these photographs? (iPhone, Android, computer)
