Abstract
A multi-camera capture system includes an audio synchronization marker to provide synchronization marks with the video streams captured by the multi-camera capture system. In one embodiment of the present invention, the audio synchronization marker generate a plurality of substantially similar synchronizing audio signals. Each camera of the multi-camera capture system records a synchronizing audio signal with the video stream captured by the camera. The synchronizing audio signals contain synchronization marks which are used to synchronize the video streams of the cameras.
