Creating and Activating the Capture Action Workflow

Manual Trigger

Select Manual to trigger capture of live video manually, using the Record button in the
Lightspeed Live Capture web application.
In and Out points. When checked, adds the OUT and IN control buttons to the
workflow instance in the Live Capture Classic web application (only). See the Live
Capture Classic Web Application appendix in the Lightspeed Live Capture User Guide for
details.
Note: If you are using the Lightspeed Live Capture web application to control
capturing, you must set the Trigger option to Manual so the web app can control the
recording of input channels.
Enable VDCP Control. When checked, Manual capture can be initiated using a VDCP
start command. The source must have VDCP enabled in the source configuration.
VDCP Port. Select the port to use for the VDCP commands.
Set Base Name with VDCP Cue Command. When checked, the BaseName token is
filled with the text included in the VDCP cue command.

Recurring Segment Trigger

The Recurring Segment trigger enables you to capture files of the duration specified.
The Recurring Segment trigger record start is controlled in the Live Capture web app,
unless Begin recording on workflow activation is selected, in which case, the recording
starts as soon as you activate the workflow.
Segments are created on logical time boundaries based on the duration selected. For
example, if a 15 minute segment is selected, the segments will start and stop at 00:00,
00:15, 00:30, and 00:45. Only the first and last segment will start or stop on a non-logic
boundary.
The first and last segments captured could be a shorter time than the specified
duration, depending on when the recording start and stop commands are initiated. The
captured files are frame accurate, so the files can be played continuously from one to
the next with no dropped or added frames.
When capturing a recurring segment, Capture tries to start new segments at the exact
start of a minute, and the job name reflects this in the naming convention: record-
HH:MM:SS:00. If the start time is only an estimate, the name reflects the estimated start
time of the segment, and the delineation for seconds is omitted from the name: [base
name]-~HH:MM. If the service fails to retrieve a time code but the source is not in a LOS
state, the name is [base name]-initial.
Segment Duration. Select the duration of the segment. The options are 5, 10, 15, 20,
30 minutes, and 1 hour. The default is 5 minutes.
Note: When you set the Primary Output of your workflow to use the QuickTime Open
container, you should also set the Default Duration in the QuickTime Open general
configuration to the same duration as the segment duration.
