Does this rumbling noise sound like the idler pulleys?

Got the belt off tonight and took a look. I'm not completely sure what I'm looking for to know if the pulleys are "bad" or not. I took a video of me rolling them, would anyone mind taking a look and letting me know how they seem?

I'm not sure that anything I'm hearing here would equate to the noise I hear in the original video I posted, but maybe that's all it takes?

Thanks as always for the help!

That bearing you rotate by hand is gone. Should be basically silent when it is good.

Thank you so much! So the first and second ones in the video ( the upper and lower idler pulleys )? The tensionser pulley doesn't seem to make noise.

Looks and sounds to me like the first two you spun need replaced. The first one may be louder and definitely the one causing most of your noise, but the second one isn't far behind. When it spins freely like that, it means that the grease is gone. The third one is quiet, and quickly stops, which means it still has grease.
