Loose chain?

Hi guys, recently I noticed some knocking sound on the back while moving, so I went to one empty area, took off my helmet and turned around while moving (real slow) to hear it and it seemed like it was coming from the chain.

So I thought it could be a loose chain. I checked it and it seemed loose and got convinced it was that, but then I remembered that I should find the tightest part of it and when I did it, it seemed like it wasn't a loose chain. Just incase, I created 2 short video examples:

https://www.youtube.com/watch?v=vcpwF_SC6Gk - This is what made me think my chain was loose. It isn't hitting the swingarm btw.

https://www.youtube.com/watch?v=3RjY2QPmayE - And this is (I think) the tight spot.

So my questions are, do you guys think it's loose and needs adjustment? I measured it and it seemed around 2cm slack, but for all I know I could've totally f'd it up even tho I was looking at the manual. And wtf could be causing that sound? I will edit the thread later, with more details about the sound.
