Good question

I get 100GB with primal premium. Sometimes, I host photos on my Start9 server with Gitea too.

Most likely you will. Free storage does exist but it's often limited on quality or length of video. If you want to upload a lot of videos or long videos, you are most likely going to have to pay for a nostr storage provider or run your own. This would include nostr.build or Primal premium for example.
