Chirping noise coming from the engine compartment

[MetalGrand]

My 2008 Ram started making chirping noises. It starts making this noise after the truck has been running for 10-15 minutes. I am guessing it is like a belt or a pulley but I am hoping to narrow it down.

I have a video here. Thanks!

sounds like a pully needs some lube. sounds like metal against metal.

Sorry I am a little new to this kind of stuff. How will I be able to find out which pulley it is and how do I go about lubing it?
