For those of you creating Jing movies for students one of the issues you may have had to deal with is managing and posting the movies themselves. (Unless you've purchased the "Pro" Account and are uploading to iTunes!)
With Media Roll, Screencast.com has taken the management off your hands! Now, Math teachers can create Jing videos for sections of a chapter, save them in a folder labeled with that chapter and then embedthe Media Roll for that chapter on sites such as Edline and Moodle!
If embedding is not an option, you can copy the RSS feed from each folder, and add that to your Moodle course or Edline Content.
