panning faces in a moving vehicle

[Phantom]

Ok, here's the problem. I've got 8 guys in the back of a moving helicopter, I want to do a close-up shot of each persons face for 2 seconds, then pan to the next person, and so forth, as well as have text come up.
Can someone please tell me how to do this.

As always, all help is appreciated.
Cheers
Phantom
