Just to rule out the obvious check tension on the AC drive belt. A LOT of odd sounds can be attributed to over-tension or under-tension on drive belts. Bearings can be damaged and create a whine sound if too tight or belts can develope a sort of "slack" spot if it's too loose (but still tight enough to not squeal) which makes a sort of "rattly and floppy" sound.

The video just sounds like damaged bearings though, commonly caused by over-tension on belts. They compressors still run for a super long time with damaged bearings though, typically the only thing that kills them is the constant dry-starting if the refrigerant has leaked out of the system.

 

My sound is happening intermittently and happens at various RPMs. I turn the AC down and then up. The audible sound lessens when turning it down but stops when shut off. If I turn it back on, the sound is usually gone. It started about two months ago. I have about 98k miles. Any thoughts? I will try to compress the video to upload it.
