I never said pixel perfect, but I would be surprised if whole objects , like flaming lanterns suddenly appeared.
What this demo demonstrates to me is how incredible willing we are to accept what seems familiar to us as accurate.
I bet if you look closely and objectively you will see even more anomalies. But at first watch, I didn’t see most errors because I think accepting something is more efficient for the brain.
You'd likely be surprised by a flaming lantern unless you were in Flaming Lanterns 'R Us, but if you were watching a video of a card trick and the two participants changed clothes while the camera wasn't focused on them, you may well miss that and the other five changes that came with that.
