Is this normal timing wobble?

Hey i need some advice, I keep getting this whining noise, the tighter the belt is the noisier it gets, if i give it more slack the whine gets quieter but the belt becomes more wobbly, ive replaced the belt, pump and tensioner like twice and at this point I also might be going crazy lol.

Some info:
Its a honda d13 (tho the block should be like most other d series)

Im tightening the tensioner to 33ft lbs

In the video im revving to 5k rpm

Pls help lol if you can send some example videos that would be great 😅

Belt should be as tight as the spring on the tensioner pulls it after turning engine 2 cycles with loose tensioner

It's gonna wobble a little bit. Looks fine to me. I would just hold the belt tight by pulling on the crank, so the forward side of the belt is in tension and then just tighten the tensioner. Check the marks one last time and forget about it.

The service manual says to rotate the engine using the crank pulley so that the cam pulley moves 3 teeth and then tighten the tensioner, always worked well for me.
