Video of weird sound from under the hood

Hi guys, I've had a weird sound coming from under the hood for a long time now and I wanna fix it already. It seems to happen only after driving it for a while, like when it's really warm. I'm thinking it's a bearing that needs to be replaced, but I'm not 100% sure which one.

What does it sound like to you?

Thanks!

I was going to say bearing or a pulley. Better pray for a pulley.

Does it get louder when you rev it?

This is how my sounds and its the bearing


If you take belt off it and turn the SC pulley it should turn freely without sound...if it makes a sound while you turn it by hand it could be your SC pulley bearing
