Did the garage who did the cambelt do the waterpump at the same time? They certainly should have done, can you see it weeping from the waterpump?
I'd take the auxiliary belt off and see if the noise is still there, at least then you've got half an idea of where to start. Sounds alternatorery to me, but dead bearings tend to sound much alike and videos distort the noise.
