The concept (something I think already exists) is simply that the room is intelligent and energy efficient, so the lights come on automatically when someone enters the room.
Now I may be wrong about this, but I'm pretty sure that shot actually wasn't artificial. From what I remember, there was someone off camera flipping the switch as soon as the door was opened. I think the artificial look had more to do with his ML settings I mentioned above.
Oh, they definitely exist. Our company just moved into a new space and renovated for the move. All new energy efficient light switches that turn on when you enter the room. It is nothing more than a motion sensor where the switch would be. The problem with them is that they turn off even when you are in the room. During a meeting the light will turn off several times until someone waves their arm around for a few seconds. We even have them in the restrooms where the switch is at the entrance door and out of sight of the stalls. Yes, there has been at least one person that ended up in the dark.
On a more direct note to your video, you are depicting the lights to come on as soon as the door opens. In fact, at least with what we have, they come on as you walk past the switch. I don't know if they'd be sensitive enough to come on the second the door cracks open, but maybe.
It's a moot point anyways. I'm only cognitive of it because we just had them installed at work. I was just wondering if the lights coming on as someone enters the room (as opposed to the door cracking open with a tight shot of the door) would better convey the idea of a motion activated light. I didn't catch that it was motion activated until you pointed it out in the above post.
Everything else in your video is so amazing that I doubt anyone would be impressed by a low tech motion switch anyways, so it really is just a moot point.
I wasn't phased by the underexposed scene, I though it was just for effect. It wasn't until it was pointed out that I realized it, so I don't know if it's that big a deal. I think it helps to add contrast from the pre scene to the main scene, sorta helps to escalate the momentum.
Just my two cents.
