After creating a Rotoscoped clip in Afer Effects and exporting with Alpha channel. I import it into FCPX and then I have a black line on the edges of the rotoscope. Why and is there a way getting rid of the line?

In the Settings Info inspector check the alpha handling. It probably should be on premultiplied.
