yes, could be a bug, but i cannot really see it "lifting off" the shirt. i don't think it is a light beam, because it seems to have a distance from
the shirt.
Yeah, I tried to slow it down frame for frame, but lack software for that. As best as I can tell when it moves it seems to go long then short, then
long, like what I would think a moth fluttering its wings would look like. It seemed to loop like moths do as well.
I don't think it's an orb, to me it seems to come from behind his shirt then "flys" towards the light shining on the other guys face, so i'm
gonna call moth, excellent find though, well spotted.
