I frankly don’t see a way for federated video to happen unless uploads are severely limited or it’s paywalled. Even with YouTube’s wild compression, you’re looking at several gigs for a single 4k video.

Honestly the fact that YouTube exists is a miracle. Video is still just monstrously large.

Is size really the issue though? I can torrent more than I can store on my hard drives.

Seems like you could build a video streaming service on that. (Actually I think some people already did this.)
