When you have a private video, you control who gets to see it—whether it's a personal family moment, a company training, or a draft you're not ready to share publicly. Instead of making it widely available, you set permissions so only specific people can watch it. This means you can share a link with a select group, and others simply can't access it without your approval. It's like having your own little screening room where you decide the guest list, keeping things safe and intimate.
