There are four options concerning visibility:
- Only i can see this video
- Only people with the private link can see this video
- Anyone can see this video
- Only users of this instance can see this video (not relevant, TUperrTube is not federated with other peerTube instances)
At the moment there is no reliable option to make your content available only to a select group. We are working on a way to make this a possibility, but as of now we do not when it will be implemented. Currently the closest you can get to an exclusive group of viewers is the 'private link' option, with the caveat that published links can of course be shared with outsiders.
