It's not from any video.
It was made for FLASH magazine.
Sometimes they have videos you can see online.
Those videos coincided with the issue that was released in either NOV 2015 or DEC.
So if you want that video, thats the only place to get it. From that link.
Theres a way to retrieve it from that link, I just don't know how.
If I knew how to retrieve it I would upload it. It isnt that big of a file.
If you can't figure out I guess theres always screen record.
