Link to Video inside OJS

Is there a best practice to embed links to video of presentations at our conference as “Additional Content” on our OJS site? We would want the links behind the login so access is limited to those who have paid access to our journals? I saw the other postings regarding video, but one link is expired and one talks about video embedded in PDFs. I would prefer to have links in OJS that can forward either username/password or other keys to a service like vimeo.
Thanks, radjr
