As your video pointed out the knocking noise up front can come from a number of places within the front suspension. My first failure was an air spring module and the SC replaced it. Then within a year the knocking came back. Sounded exactly the same to me. They once again replaced the air strut but could only do one so I had to take it back when they got the other part a month later. In all cases the SC used the "chassis ears" to identify the knocking noise.
When they went to replace the other front air module the tech noticed the looseness of the front link and saw that the boot looked like it had a crack in it. So they replaced both links and did not swap out the other air module. Voila. Knocking problem gone.
So while this thread is about the front "air" suspension, it would be nice to have a sticky at the top directing people to have the links inspected first. Some may have gone that route first and are looking for the air module issue here and others might not need to go here at all like you.
I agree a master thread that points to the various front end knocking threads would be good. And then don't get me started why we have to post this issue in both the MS and MX forums when the problem and solutions are often the same. Please TMC come up with a forum for common MS/MX topics.
Anyway your video is still good even though it's not in the perfect place.
