Karaoke effects with KDEnlive?

First of all, it's my fist post and I am very pleased by join this forum.
So, my point is:
A few years ago, when I got involved in fansubs, I used to make karaoke effects using Adobe After Effects.
Now I am trying to find a Linux alternative. So, is KDEnlive able to do it?
(Sorry for my bad english)
