I'm pretty sure the point Q was referring to was this one, and then Q posted about a minute afterward.
Pointing at the person with the camera up? Not sure. There were a few of our signs in that area
Also around this time he gave a little wink and a nod right where the red/gold Qanon sign person was standing, when they had it down. He wouldn't really look at it when they were holding it up.

Another angle of the point. Looks to me like he's pointing at the white poster closest to the camera. I'll see if I can figure out what it says
It was another blacks for Trump one. So I'm not sure.

This one is the best with a clear acknowledgement. Jump to 7:05.
Still think that was the one he was pointing at. Was right in that area
