I seriously do not think that is any type of python. If you watch the video and note the tree to the left of the home owner I think that is the same tree the snake was on. Now when you see the tree with the man in the video it gives you a much clearer idea of the size and girth.
I would say ball park of 7-8ft at best and perhaps a bit thick for a rat snake but by no means a record setter.
