To be competitive they need 4K presets and formatting for all the professional tool exports. The relays will need non-relational database architecture running on excellent database hardware with an abundance of storage. Any individual willing to run their own relay through a decentralized content creation client, will likely have either original content, or solid pirated content, instead of just disposable re-upload spam ripped from other easily accessible free sites.

Centralized content creation clients however, ones that attract users or even advertisers, would need to censor and curate their users' uploads regularly. Otherwise it won't work, because intellectual property warnings and cease & desist letters will spam their inbox. Live-streaming will work until someone attracts a big enough crowd (and thusly Zaps) by live-streaming PPV events, etc. So like, what's the purpose of trying to recreate another dime-a-dozen centralized platform that censors, and pre-scans user uploads with third-party software, etc? So the ownership can brand it with a bright orange ₿?

I don't know what I'm getting at here and got lost. I think the Nostr relay situation needs a couple years of work
