A broadcast management system creates, manages, and streams a broadcast of an event from videos captured from multiple cameras. A video capture system comprising multiple cameras captures videos of the event and transmits the videos to a broadcast management server. The broadcast management server generates a website or other graphical interface that simultaneously displays the captured videos in a time-synchronized manner. A broadcast manager user creates a broadcast by selecting which video to output to the broadcast at any given time. A broadcast map is stored for each broadcast that includes all of the broadcast decisions made by the broadcast manager user such that the broadcast can be recreated at a later time by applying the broadcast map to the raw videos. Using a viewer client, viewers can browse or search for broadcasts and select a broadcast for viewing.
