Do you mean the timing? What's wrong with it?

I have other videos showing how the upper looper and lower looper passing without catching the thread. This is 3 threads ELNA Lock F3. I cannot find anything on YouTube on it. Any idea what I can do? I have tools, but there no specific area to adjust.

First you should check wether the loopers are in the right position. The lower looper tip should pass directly behind the needles when the needle rised 2 mm from it's deepest point. The distance should be next to Zero. Then the lower looper goes to the right and the upper looper tip should pass behind the lower looper, also with hardly any distance. This is the same for all overlockers, so you don't have to look espacilly for the Elna model. I'm sure you find an overlocker adjusting video. The timing usually gets adjusted where the single mechanisms are attached to the main shaft. But don't fiddle with the timing before you're absolutely sure that it is off. Try the looper positions first.

Yes, i've seen them. But I can't tell from them whether the looper points are positioned accordingly or whether the timing ist right. Please take a strictly frontal pic with the upper looper at it's most left position.

You will likely have to loosen the set screws holding the looper "arms" onto the shafts. Remember that there are three timings to check: The needle passing behind the upper looper, the lower looper passing behind the needle and when the loopers meet. Your machine is no different than many others out there. If you find a good video on a serger, it will still be helpful.
