Stop video autoplay in Safari for iOS

Does anybody know how to disable video autoplay on space.com?

I see the video auto-plays, although it does so with audio muted. I looked at Safari’s website settings, and “Stop media with sound” was checked. I’m not sure how they do this. It would be more annoying if websites I visit more frequently did this as well.

Hello Beklutch,
I’m aware of this settings in macOS Safari, but I read such pages on iPad and iOS Safari has no such setting. Sorry, my pointing was quite incomplete.
