I think generally, but not always, the standing routine is at the featured TV table. Obviously, the producer instructs the dealer to delay the hand to create tension for the broadcast. Players can pace, turn to the rail etc.
However, it becomes less common when they show outer tables near the bubble when most just sit there and await the cards.
All that said, if you truly subscribe to the 'standing' all-in theory, do not forget there is another flourish or two - that of putting on a jacket and backpack as if you are truly exiting stage left. Some sort of reverse psychology on Lady Luck...perhaps a little unconvincing when you are at home already.
