You are right. I also did not succeed cutting somewhere else than at the
keyframe boundary.
It looks like I was confused by the brightness of the cut point. When I use
-ss 0.5 -t 3
-ss 1 -t 3

I got the same beginning cut point which is always the keyframe but for
some reasons one of them is darker. I was confused at it when a movie was
quite static.
Anyway it works fine now for me.
