In an embodiment, method for mobile video mixing includes receiving a plurality of video streams at a mobile device corresponding to one or more cameras capturing an event. The event may correspond to a live team-based sports or a public event. The method further includes choosing a group of video streams intended to be previewed at the mobile device. In a successive progression, the group of video streams are combined to generate a combined video streams such that the combined video signal provides a simultaneous preview of the group of video signals when displayed on the display screen of the mobile device.
