Universal Capture allows users to choose whether or not to stream their recordings live from the Capture Details page.
The same limitations apply to instructor-generated ad hoc live captures as they do to admin-generated scheduled live captures. Those are:
- You MUST select a section for the capture; Saving your Capture Details is disabled when Live streaming is toggled without selecting a publishing location.
- You may need to allow a minute or two for the Live stream to begin after the recording starts. This is to accommodate the necessary server configuration and allocation of the ports required to stream the capture live to students.
How do I know that my recording is live streaming?
- A red LIVE badge will appear in the UC UI
- A green LIVE badge will appear next to the new class in the Class List
When checking the Class List, this may be a good opportunity to add a presentation, check live attendance, manage Q&A, etc. see Live Streaming for Instructors for more details.
Network and Bandwidth Requirements
Live streaming your recordings may be impacted by network and bandwidth limitations which could interfere with streaming performance.
- Use a wired network connection
- Do a single-stream recording (A/D or A/V)
- Limit the usage of other potentially conflicting or intensive applications
- Ensure your computer meets the general Universal Capture Specifications
Live Streaming Upload Requirements
- Up to 2.0 Mbps for single-stream
- Up to 6.0 Mbps for dual-stream
- Outbound UDP ports to be open
Check to see that your upload speed meets our requirements here: Global Broadband Speed Test
Check to see if your ISP (Internet Service Provider) is blocking or filtering outbound UDP traffic here: Is my ISP filtering my outgoing network ports?
UC Personal specifics
Universal Capture: Personal provides the same ad hoc live streaming capabilities that other managed capture devices do, but with one specific difference.
UC: Personal does not allow you to set a custom Capture Duration, the default live stream length is 4 hours. When you start an ad hoc live stream, UC will keep recording and streaming until you stop it, you close the application, or the 4-hour limit is reached.
If you try to close the application during an active capture, you will be prompted to be sure you want to stop recording and/or streaming.
In order to save on network resources, UC: Personal will not upload the current live recording in the background like it does with VOD captures.
Universal Capture: Personal requires you to be Working Online in order to stream live. Working Offline is not supported.
Initiating an ad hoc Live Stream
- Launch Universal Capture.
- Log in (if not already authenticated).
- Click the pencil icon or title to launch the Capture Details dialog box.
- Enter a Title, add a Description or Tags as desired, and select a Publishing and Class location.
The publishing location and class selection lists are searchable for long lists. Click into the field and start typing to search.
- If applicable, enter a Duration for the capture. (Not for UC: Personal, see above section)
NOTE that the Duration field is limited by upcoming scheduled captures. Captures can be initiated for any duration (up to the 8-hour maximum) up to the time the next recording is scheduled to start and will automatically stop to allow the previously scheduled capture to occur.
- Click the Live Stream toggle.
- Click SAVE to return to the preview screen.
- Select and preview the inputs you want to capture.
- Click Record.
A countdown appears after which the Universal Capture window minimizes and the capture begins. See Controlling a Capture for details on additional options during a recording.
NOTE that it may take a minute or two for the Live stream to begin as it connects to or starts up a streaming server even though UC is actively recording. During this time, students in the Classroom will see a "Waiting for Live Stream" message. In the UC UI, instructors will see a similar message that also counts down an estimate of time remaining until the live stream kicks off.
