How Do I Display Videos Hidden From Vimeo?
If you’d like to hide your videos on Vimeo but show them on your site, you will need Vimeography Pro.
To display videos hidden from Vimeo, first mark your videos as hidden from Vimeo and then place them in a Public showcase. You then use that showcase URL as the source for your gallery. The videos won't appear anywhere on Vimeo, but will still be accessible by Vimeography.
Vimeography currently requires videos to either be Public or Hidden from Vimeo. Password protected or private “only me” videos will not work.
