The practitioner, in the video is Thich Man Tue, who is affiliated with Thich Nath Hanh's Tibetan Buddhist tradition, in particular with their Deer Park Monastery in California.
About half way through, you'll come across their version of Eight Pieces of Brocade -- maybe the most practiced qigong sequence there is.
