I could recognize the belt tensioner sound. I guess the other knocking sound comes from a piston.

Sounds like a valve tap and/or sticky valve.

That's no my video, but I made one just like it. I took off the valve cover and everything is perfect under there. Currently putting it back together to continue the search for the knock.
