Abstract
Methods of encoding a live video signal in a video encoding system including a plurality of video capture and encoding subsystems include providing the live video signal and an associated time code signal to the plurality of video capture and encoding subsystems, starting video capture and encoding in a first one of the subsystems at a first frame of the live video signal, starting video capture and encoding in a second one of the subsystems at a second frame of the live video signal that is later than the first frame, generating encode frame timestamps for the second frame in both the first and second video capture and encoding subsystems that are synchronized across the first and second subsystems, and associating the encode frame timestamp with the second frame in both the first and second subsystems. Related systems are also disclosed.
