Clip 1:
I'm curious if the Warrens were innocent bystanders or were part of the deception, but the part with the girl moving the chair is pretty funny. I used to play similar tricks at the table when I was a kid, but I was just idly playing around, not trying to simulate a haunting.
The moving table in the Warrens' investigation is also interesting. Was Ed Warren really in the room doing religious provocation, as is implied in the clip? Or was his voice dubbed in? Of course, the chair and tables all move toward a single point, so I assume Grant must be hiding in the corner. OK, OK, maybe someone else knows how to use a piece of string. Also, the table and chairs look a little too still when they're not moving around on their own– none of the normal dot crawl you see in video. I would be unsurprised to discover that freeze-frame was involved. Just an uninformed opinion.
I can't decide if the moving chair at the construction site is string or computer graphics. Something about the movements look very CG to me, but of course it could just be sped-up footage or an extremely steady hand on the string.
Clip 2:
I hadn't watched Clip 2 before. The intrepid investigators with the Pink Lady seem to be falling victim to paredolia, but I can't rule out hoax. I invoke Stephen's Law ("You can't analyze crap") on all of their apparition photos. OK, perhaps "crap" is too strong a term, but blur is blur.
The strange, cordlike photos taken by Norma are classic camera-strap photos. These still get disseminated as actual ghost photographs, and that astonishes me. "How can this be," people ask, "when the camera strap is black and the image is white?" "Because it's caught in a flash," I reply, "and exactly how did you get into my house?" Oh, sorry, that only happened the one time. Anyway, the loops are always on the right (OK, one's up from the bottom) and have the same segmented texture as the strap on one's camera. The loser in all of this, of course, is baby Carissa, who is being raised to believe that she's constantly surrounded by ghosts. Here's hoping she's grown up OK and is having a good laugh over all of this by now.
And finally, we have a group of ghost hunters frightened by mist. Gman is probably right and it's probably breath condensation. I don't know. I wasn't there. All in all, mist may look spooky but is not paranormal. Wonderful quote: "Regardless of what is fact or fiction, residents and paranormal experts believe that this house is haunted." I'm sure they do.
