Capture Action Overview
The Telestream Live Service and Capture action are Vantage features in a Vantage
domain when running on a Lightspeed Live server. The Capture action is added to
workflows created for ingesting live and live linear media directly into production, post-
production, and broadcast workflows.
The Capture action inspector enables you to select and configure live streams for
processing, filtering, transcoding, and output. Capture supports SDI, RTMP, and
Transport Stream inputs only. You can also use the action to insert leader, filler, and
trailer media from files into the live stream.
CAUTION: Workflows containing more than one Capture action are not supported in
the Live Capture web application.
The container and codec selected in the Capture action specify the encoding and
format of the capture operation. The encoded media is captured to a primary file stored
locally or copied to external SAN/NAS storage, also based on the Capture action
configuration. At the same time, a secondary proxy file may also be configured and
produced.
Note: Most MXF files containing IMX, XDCAM or AVC Intra, and QuickTime Open files
(Capture action only), are created in such a way that they can be opened for editing/
playing (in Adobe Premiere Pro CC, Telestream Switch and other media applications)
while they are still growing during capture. Check with your edit/player application
software documentation for details about supported formats.
As a Vantage origin action, the Capture action can be used in Vantage to begin a
workflow, and can be the only action in the workflow. A capture workflow can include
additional actions, such as a Copy or Move action, which can output the captured file to
an additional location.
You use the Lightspeed Live Capture web application to start and stop recording
selected sources and to pause recording. For information about the Live Capture web
application, please see the
Lightspeed Live Stream User Guide , available on the
Telestream web site. The Lightspeed Live Capture Web API can also be used to create
custom programs to control capture workflows. For details on the Web API see the
Lightspeed Live Capture Web API Reference at the bottom of the Live Support page on
the Telestream website
.
This action is open workflow capable if an Open Workflows license is installed; right-
click the action and select Workflow Mode > Open. Open Workflows must also be
enabled in the workflow and in the Vantage Management Console Settings.
