... I mean, I don't see it in that third tab in Amethyst.
It's because flare is not including the mime type of the video. So amethyst doesn't even download (we only download the videos we support and can play)
But when I link to the video event, it works even in Amethyst. See here: nostr:nevent1qqsg85jkk9pwjnp47vd5d63qntttrumcarm8prm5wy6hkzfvlfafprgpz3mhxw309ucnydewxqhrqt338g6rsd3e9upzp2x32cxk5era2qtfj9njgmer0vm0ky3l3ytglks3m36r2vl7c7sgqvzqqqqqqysquqmd
Yep, the content type filter is just for the middle feed. Otherwise, there is a lot of junk that gets downloaded that the app can't display.
