Media Manager
The Media Manager handles the media, or files, that make up the rundown content. To install it, begin by downloading the latest release of Media Manager from GitHub. You can now run the media-manager.exe file inside the extracted folder. A warning window may popup about the app being unrecognized. You can get around this by selecting More Info and clicking Run Anyways. A terminal window will open and begin running the application.
You can now open the Sofie Core, http://localhost:3000, and navigate to the Settings page. You will see your Media Manager under the Devices section of the menu. The four main sections, general properties, attached storage, media flows, monitors, as well as attached subdivides, all contribute to how the media is handled within the Sofie Core.
