If you add a nonpublic (Anyone, Password, Hide from Vimeo, or Private) video to a showcase, that video's visibility will depend on the privacy settings of your showcase. Learn more based on your showcase's privacy setting:
Public showcase
Putting a nonpublic (Anyone, Password, Hide from Vimeo, or Private) video in a public showcase does not make the video public. Only you will be able to see the video within the showcase.
Password-protected showcase
If you add a nonpublic (Anyone, Password, Hide from Vimeo, or Private) video to a password-protected showcase, anyone with the password to the showcase will be able to watch it unless the embed privacy setting of the video doesn't allow it to be shown on your showcase's domain. This setting allows you to share groups of nonpublic videos with a specific audience.
Hide from Vimeo showcase
Setting your showcase to Hide from Vimeo will allow you to embed a playlist, but your showcase won't be viewable on Vimeo.com (this setting is best for users only looking to embed their videos).
Only people on my team showcase
With an Enterprise account, you could also set your showcase to Only people on my team, which will restrict the content of the showcase only to team members you've added to your account. This is helpful with sharing internal content within your organization.
