I think this is the second time in a week (the first being the "Googlebook") that Google's promotional announcement video showcasing UI is so full of special effects, dramatic pan/zooms, and woosh sounds, that I have no idea how the final-end product actually looks or works.
I watched this video too, and like the google book one, I have no idea who this product is for
I had to stop it because it was making me dizzy trying to focus on what was shown
It looks like an output of one of those AI video editors that some (often vibecoded) startups use for their product launch videos. Just drop some assets in, and it spams witty taglines with dramatic transition effects.
