Fraps if it's minecraft on PC.
if it's the xbox 360 version you'd need something else that uses external cap cards.
Edit: But I believe Fraps is a subscription program. There are a lot of freeware stuff out there that might be better to use while his interest is in it's infant stage. If he gets more interested later on then paying for fraps might be the way to go........Thats just me though, don't throw money at things right away.
