I got a response from the house archives and they don't carry any of the footage from the SOTU. other sources they said may have video is CSPAN, Library of Congress And the U.S. House Recording Studio.
For Library of Congress, they recommended specifically "congressional floor proceedings" and recommended googling "congressional floor proceedings library of Congress" or going here: www.loc.gov/avconservation/collections/congress.html
They said we can also try contacting the U.S. House Recording Studio directly I have not been able to find their direct phone number, but the Chief Administrative Office of the U.S. House, which oversees the House Recording Studio, can be reached at 202-226-6660
