It sound like one or both Idler Pulley, #5 in diagram..
The only way to find out is remove the belt and manually spin the pulleys as fast as you can. If it spins fast without any drag, it must be replaced.

THE SOUND SEEMS TO BE COMING FROM THE BOTTOM OF THE VEHICLE, IT DOES NOT SEEM TO BE ENGINE RELATED. THE SOUND THAT CONCERNS ME IS THE ONE YOU CAN HEAR AT THE 0:10 SECOND IN THE VIDEO.
