this article seems to only describe what you can see in the video (already linked in other comments) and does not add any value, apart from advertisement, but that value doesn't go to the reader.
Doesn't add value for you, perhaps. Because of the article, I didn't feel a need to watch the video - and since I strongly dislike watching videos (they tend to be noisy and demand more of my attention for a longer time than I am willing or able to give), it worked out quite well for me.
I can't view the video here, so reading the article was valuable to me.
