Program is typically a one track clip normally used to save broadcast assets, such as commercials.
Program is usually set up by the MIS administrator in the form of as-run files. This will automatically insert programs into the system using the hot folder.
This feature works much the same as Bookmarks. You can search for a particular program. Hovering over the program opens the player and allows you to view and share it.
To manually add a program use the add program icon at the top of the page. This opens the New Program page. Select a channel and use the <Mark in> and <Mark out> icons to create a new program much like any other clip.
