I understand the original act like this was performed at Cirque du Soleil. It's not magic, just acrobatics. Those in a hurry can skip the introductory hype by starting at the one-minute mark. The performance will end - dramatically - six minutes later.
She is mic'd up for sound, so her breathing is sometimes a bit intrusive, but that's part of the act. As is, I presume, her occasional hand tremor. But overall it is quite impressive.
