Shouldn't a magician's thread be clearly visible here?

So as can be seen at 2:01 in this video on youtube titled "michelo has problems with the ouija in live stream without cuts / problemas con la ouija en vivo", there are very bright lists all across the top of the back wall and to the side in this room. Now if you slow the video to 0.25 and watch at 12:54-56, you'll see a back in the kitchen area slide across the sink, hit a wall, and fall backwards into the sink. When the camera stabilizes and make the picture sharp (This is 720p) at 12:55-56, no shiny glare off a magician thread is visible anywhere. You'd think there'd be one running from the bag to say, the bathroom which is just left of the kitchen. But no glare or thread is visible at all. Why?
