How are you trying to upload? I'd be happy to host vids for a fellow gun nut at happy Tavern for ya. It would be a bit tedious at the moment since I'd have to manually put it there.

You have your own domain, you could host the vid on your site and link straight to the video. I might can help you do that too.

I can also show you how to make a NIP5 verification with your domain.
