The only way I can find to add additional people to view my videos from say a meeting recording is to navigate to a list of my videos then use the pencil/edit icon and add them under the 'Permissions' section.
Intuitively I would expect the 'Share/Email' workflow from the main video window to do the same as I have select specific users to send it to.
The permissions UI should be exposed in the various views of my content in a simply manner.
Thanks
