Record All
—Select
Record All
to record the currently ganged channels.
Record All
operates in two different modes depending on whether
Time-Shift
has been enabled in the
workflow. (See the Capture action man page for details about Time-Shift.)
•
When Time-Shift is NOT enabled
in the workflow, all channels start recording
immediately with no attempt to synchronize the start timecode.
•
When Time-Shift has been enabled
in the workflow, the system attempts to syn-
chronize all of the selected channels to the exact same start timecode before start-
ing the recording. When recording starts, some portion of the frames in the Time-
Shift buffer are added to the start of the recorded file (going back in time to
included frames from the past). As a rule, add 10 seconds of Time-Shift for each
ganged channel. For example, in a Live Capture system consisting of three servers
capturing 12 channels (4 per server) each channel should be given 40 seconds of
Time-Shift (4 channels X 10 seconds per channel = 40 seconds).
•
Note
that all ganged channels must use the same timecode source in order to be
synchronized to the exact same frame during the gang recording operation.
