The noise from my end is an internal engine knock. It could be bearings or lifters. Hard to tell from the video but it is definitely engine noise.
I would have the oil pressure tested to be sure it has pressure. If it does, then something happened internally.
Oil Pressure (Hot at 2,000 RPMs) 40-60 PSI
You need to remove the oil pressure switch and insert a gauge into the hole and run the engine. The pressure is posted above. You can rent the tester at a parts store.
