With Media Mover 2 having significantly changed its architecture, the possibility to import and export data has gotten much more interesting. Because Media Mover's configurations now are mostly containers for steps which define the actual things that happen to files, it is possible to export and import both full configurations and individual steps. This is helpful for example if you are tweaking your video conversion process on your development server and then you can export the tweaked settings to your production environment. Mark Sonnabaum has been leading the way getting the integration with CTools done so that there is a familiar interface for getting data in and out. Check out a screen cast that Mark did to show the process in action.
