1. When Creating a New Video or Editing a Published Video - navigate to the Release Settings.
Release Settings can be updated and selected when uploading a new video, or when making changes to an existing video.
2. Determine if the video should be open to Anyone or Only Subscribers
Let's define what these two options mean:
Anyone = visitors and subscribers can view this video, no subscription required. A great example of free videos are "teasers" or "trailers"--anyone can watch these, determine if they're interested in the content, and then become a subscriber to watch the secured content the teaser or trailer is promoting. Pilot episodes or very highly-ranked episodes with high conversion rates are other great use cases of free videos.
Only Subscribers = this video will be locked to visitors and require a subscription to your channel to view it. This is typically the default setting for all videos.
3. Previewing Video Settings on Projects
Below is an example of a video that is locked - you cannot watch it, and it contains a lock icon on the thumbnail.
Below is an example of a video that is available for all to view - there is no lock icon, but instead the length of the video is displayed.
Below is an example of a locked video "landing page" where the content of the thumbnail is displayed, but a visitor is not able to watch the video. A visitor must subscribe to your channel in order to continue watching.
