In order for a video to be sent directly using a configured broadcast provider from Dubb, or to be included in Campaigns or Automation, the video must be "Shared".
In order to make a video "Shared", visit the Video Page and be sure to select the "Share with Team" checkbox:
"Shared" videos are accessible to members belonging to the same team.
Selecting the "Share" checkbox does not change the privacy settings. Videos will still be Featured, Private, or Draft.
