Is this Rod Knock?
No, does not sound at all like rod knock to me.
Rod knock as a more metallic ringing sound, higher pitched. Yours is a more deeper thud.
I'd try things like:
Temporarily remove serpentine belt, see if noise persists (rules out all belt driven accessories and crank damper)
Use mechanic stethoscope to try and isolate if noise is front, back, top, bottom, etc.
See if noise changes when pressing clutch
Did anything change recently, any work done, etc?
