Can someone take a look at this latest video that shows the rumble a lot better and let me know if I'm on the right track with the pulleys, or is this loud enough that it could be something else?

Regardless I'll be taking the belt off to check the pulley bearings as @JFP in PA mentioned, but wanted to check in case this is something else that I would need parts for so I can get them ordered.
