I can't even make out a face from the video.
There's nothing, for me, that says it's the Virgin Mary.
Maybe if I could make out a clear face, or better, something that indicates "This is the Virgin Mary", I would have bought it. Not convert to Catholicism, of course!
The image is far too ambiguous, in my opinion.
I believe it's a stain on a window.
