How to use Matinee Make Camera focus on special Actor?

Hi every one:
I want to use matinee making a cut scene.
I intend to focus on a moving Actor and the camera make a circle orbit focus on the actor.
When level start, Actor will moving by matinee, and the camera also moving by matinee.
Any one has good idea?
Thanks!

If you are animating them both through matinee, you could just manually key frame the camera to look at it.
Other than that you could take a look at the ‘Blueprint office’; It has cameras which are animated using the timeline and then track an actor when they collide with it.
