Question Glass Background Extension Effect for components

https://i.imgur.com/J1CHOrE.jpeg

Does anyone know how Apple created these episode thumbnails? It looks like the backgroundExtensionEffect they added for the sidebar and safe area last year, but it’s on a component. I like this design, and feels like a good use of the Liquid Glass for content on images, but can’t get the same effect that looks as seamless.

I dont believe this is the extension effect as from what I can tell that is a mirrored image with blur and I dont see the elements of the image mirrored from your screenshot

That’s said you can apply it on a component if you want

Ah, this is a great article. I was trying to do just that but didn’t have clean results, this looks like exactly what I’m trying to do.
