Priests don't record exorcisms, for the sake of the privacy of those possessed. My parish priest told me that a priest friend of his had witnessed a person walking up a wall. And if you google modern-day exorcists, you will see plenty of reports of preternatural phenomena.
But even if video evidence was available of someone walking up a wall, people would dismiss it as trick videography.
Eyewitness accounts can be compelling when there are several, and no parties have a financial interest in relating their accounts.

Completely agree; I am certain that there are people who are determined NOT to believe this evil exists.
Too ‘unpleasant’ for their sensibilities.
