• Chronological: Plays the videos as they are recorded/uploaded
• Latest first: Plays the most recently added videos first
• Popularity: Plays the most liked videos first
• Custom: Plays whichever order you decide (you can change this on the Manage menu by dragging and dropping the videos into the order of your choice)
