There are several options for cam chain tensioner problems
(although I do not hear something like that in the video)
1. Cam chain tensioner mounted misaligned:
To be checked via the oil pan, see pictures in Ibsen's Replacing the cam chain tensioner thread.
2. Tensioner stuck:
One can try to open the second, upper bolt, too. This may help to get a stuck tensioner free. But open just a turn, no idea if one could put it back if you remove it completely (although I know of someone who managed it at a 500. However he kept the adjustment nut fixed because he had to take bolt out only to retorque the head bolt beneath).
3. Cam chain worn
Below a picture of the cutout for the screwdriver check.
