To share a video during a WebEx meeting, you must use the UCF Toolkit. This will allow you to embed a link to the video that can be streamed to your attendees during your meeting.

To install the UCF Toolkit, simply follow these steps:

1. Log in to your WebEx website (Example: https://SITENAME.webex.com).
2. Click on a WebEx service tab (located toward the top of the page).
3. On the left-hand navigation bar, click Support, then Downloads. 
4. In the section titled “WebEx Universal Toolkit”, click the Download Now link.
5. Run the file or save it to your computer.

This will install the WebEx bar into your Microsoft PowerPoint program.

To embed the video into your PowerPoint presentation, simply follow these steps:

1. Upload your video to a website that is accessible from the Internet (although it can be a hidden directory).
2. Copy the uploaded video’s URL.
3. In Microsoft PowerPoint, go to the slide where you want to insert the media object.
4. Click WebEx and select Insert Video Object.
5. Paste the uploaded video’s URL.
6. Click Insert.
   The “Object Properties” box appears.
7. Click OK.
8. Your video is now embedded in PowerPoint. Save your presentation as either UCF or PowerPoint format.
