You say a video is best, even though you also say that a video isn't best for your target audience?
Accessibility makes things better for everyone, not just those people who need it. If you'd approached this with accessibility in mind you'd have realised that a video was sub-optimal, and come up with some form of text. That (while not covering everything) would have been more helpful for more people. As can be seen from the comments here.
I did design it with accessibility in mind. There is a text description right under the video, and there are captions on the video itself. But neither of those change the fact that the video is the most compelling way to communicate what we're doing.
