All my videos (onsite, YouTube, and Vimeo) were successfully imported from my Ning site. I noticed that my Vimeo videos did not show thumbnail images like the YouTube and onsite videos and wanted to correct that. I noted in the DataStore for Vimeo, no artwork urls appeared as they did in the other video lists. Hmm...
Exploring the documentation, I found that it was necessary to create a Vimeo app and enter the client codes in the module config. I did that. Still no thumbnails.
Then I foolishly tried running an Integrity Check. It deleted all but one of my Vimeo videos (along with their comments) saying the videos don't exist on Vimeo. They do! They're set as private, hidden from Vimeo, only viewable on selected sites -- including my Jamroom site. Now what? I need to get my videos and their comments back, hopefully with their thumbnail images.
