Comment (by jb_alvarado):
I am not 100% sure if this is a straight alpha, but when I render this
png's I have an option "Pre-Divide by Alpha", normally this option is off.
If I turn it on, the overlay in ffmpeg is good, without boarder.
The Problem is, that I mostly don't know, if somebody turn this option on,
or not. So it would be nice to have an option in ffmpeg to fix this.
