Webcasting a live CaptureCast presentation

If you are webcasting a live presentation, use a high-speed internet connection to ensure quality streaming for viewers. There should be at least 1 Mbit/s of upstream and downstream network bandwidth availability for SD videos, and 3+ Mbit/s for HD videos. Additionally, network ports for RTMP (Port 1935) and RTMPT/HTTP (Port 80) must be open.

You should create and schedule your live event in Capture Portal or Capture Central before you begin webcasting to inform viewers ahead of time about the event. Once you create a live event, its information and access link appear in Capture Portal's Calendar page and in the Live Event Schedule widget on the Capture Portal Home page. If you embed a live event in Learning Environment, the event remains paused in the Capture viewer until the presenter begins the live webcast session. The Capture viewer automatically loads the live webcast once it begins.

Present a live webcast

  1. On the main Capture Software screen, click Webcast.
  2. Do one of the following:
    • Select your pre-scheduled live event's name from the event drop-down list. The event names listed correspond to "Upcoming" live events in the Capture Portal or Capture Central connected to your Capture Software.

      Note  By default, the Title, Presenter, and Layout fields, and the Chat check box automatically populate with information entered from Capture Portal or Capture Central. You can change this information by selecting different options on this screen.

    • Create a new webcast by clicking the Create a new event icon and enter information for your live event.
  3. Click Start Webcast.
  4. You can do the following to enhance your presentation:
    • Click Add Media to import files (PPT, PPTX DOC, DOCX, PDF) to the presentation. This option is ideal for presenting static slides or document pages.
    • Click Share Desktop to share your desktop as screenshots or video. This option is ideal for presenting animated content such as web browsing or a software demonstration. Video mode requires more bandwidth, but you can select between image and video capture modes by clicking Options and going to the Camera and Screen tab's Screen Sharing section.
    • Click Capture VGA to share your desktop, video camera, or any device connected via an Epiphan VGA2USB capture device. If you want to explore this option, contact your Desire2Learn Capture account manager for more information.

      • Note  You can switch between Add Media and Share Desktop during a webcast if you want to display static files and images, and desktop demonstrations.

  5. Once the interface loads, you can see audio and video preview feeds in the encoder screen. Click Start to begin streaming the live webcast in Capture Portal or Learning Environment.

    Tip  You can click the Pause icon anytime during streaming to pause your live stream. Paused sections of your presentation are not released to viewers. Click the Start icon to resume streaming.

  6. When you are finished webcasting, click Stop.

    Important  Clicking Stop during a live event indicates you are finished recording. Clicking the Start icon after clicking Stop overwrites your current recording with a new recording.

  7. Click Finish to return to the main Capture Software screen.
