I'm usually the first to complain about things like that as well as I'm very easily distracted, but in this case I think it's not that bad and looks kinda nice.
I still wish websites would not only respect the disabled autoplay setting but also stop animations completely in that state. But right now it seems crashing video player UIs are the best we can get.
There's prefers-reduced-motion[1] but I don't think many sites actually implement anything for it. This one is open source though so someone that cares could submit a PR
