There's a trick for those side-by-side stills without a flicker. If able, go cross-eyed focusing between them to converge upon a 'third' image. If you've done stereograms, you'll know. Differences will show up easily as hazy and not so static if you gaze around a bit.
This is also related to how horrible eye witness testimony can be. There are good demonstrations of change blindness on Youtube. The human brain is incredibly awful at visual recall like this, regardless of advanced warning to concentrate. The longer a delay, such as by inserting a black frame in between, or diversion, the harder it is to spot differences between scenes. Here's a classic:
Aric, I wanted to upvote your answer and believed I did it, but it seems that it got gray afterwards? I really miss the possibility to correct my vote in case the click was interpreted wrongly the first time.
I wondered why there'd be any hate for my comment even as it's destined to fall into obscurity. Quite alright! :) I appreciate your follow-up. Just a few basic features like that added to HN would make a huge difference.
And was even in front of the computer, not using the phone! Still, at the moment only writing a comment like that can maybe correct the error. Thanks for understanding.
definitely an interesting video - thanks. I wonder if the detailed visual information necessary to detect those changes is actually stored but very hard to retrieve, or simply not stored.
This used to be a big problem in astronomy, before the introduction of computers. Astronomers would use a special device, called a "blink comparator", to rapidly switch between two pictures so they could see the changes between them. (This is how Pluto was discovered.)
