Hmm that doent sound like tip in knock. But you rearly need to log ecu parameteds to be sure. Detonation pre Ignition or pinging or igniion knock is usally a more high pitched tinny sound like ball bearings in a tin can.
The noise in that video sound like a mechanical noise like vvt rasp or resonance or engine bearings on the way out or low oil levels\pressure or something rattling
