To create a private video simply mark it as private when you set the video type in the video details form during upload or after when you edit the details of a video. Private videos can be added to playlists just like any other type of video.
Private videos are a very useful tool for when you want to limit who can view a specific video. Private videos are not publicly indexed by search engines but if you share the link to a private video or embed a private video others will be able to watch it.
