Well, I was wrong about the AC clutch. After a day or so of not having the AC engaged, the noise came back. I replaced all 3 belts, both idler pulleys, and still have the noise. In the second video I posted above, the sound is super clear - it's light a low knock sound that comes and goes. When the engine is making that sound, the lights dim and power is weak. It honestly sounds like it's coming from inside the engine.
Edit: My oil was low about a quart, and I've been reading about the hydraulic timing chain tensioner. I just filled it back up - could that be a contributor? Will see if it goes away tomorrow.
