Yeah, I know on Lemmy we’re typically all about self hosted or federation friendly content, but there are reasons YouTube is the king of video hosting. Video hosting is expensive and hard to pull off.
If you want free services, your option is pretty much limited to YouTube. There is also PeerTube if you can find an instance that suitable for your video. If you don't mind paying, then you'll have more options such as Vimeo or Cloudflare Stream, or even host a PeerTube instance yourself.
