Oh no, you killed this with the scrolling capture thing. Consider that people are on mobile and experience the behavior at the bottom of the page as a straight up bug, until they realize they need to keep scrolling with their thumb to get what they previously assumed was a video to progress. I don't know who came up with this scrolling paradigm to begin with, but it's just a bad idea. Shame too, because the actual product/tool being showcased here looks like it could be pretty useful.
