hm, ya to host videos thats not really relays doing that.  media on nostr is just links.  nostr.build has the nice integrations but any link will work. so it depends on how eaay they want it to be.. like if they expect the nostr app to upload, create link, etc then all the services that do that are pay in sats. but if they upload somewhere else, get the link and paste, then there are lots of ways to do that kindof...
