At this time, there is not a specific function for adding a video to an Event Registration, however, you could add a link to the video, or embed it through HTML. 

The video can be added to the Description of the Event Registration.
  1. Go to Core > Events > Registration Forms & Attendees
  2. Approval
  3. Event Registration

  5. General Info tab
  6. Scroll down to the Description text area

To add a link to the video:
  1. Navigate to School Website.
  2. Select Content > Media > Video
    • If your school does not use Blackbaud’s School Website System, or if you are not a Page Manager, you can access content through Core > Content
  3. Upload the video to a video category.
  4. Click the URL button to the right of the video in the category.
  5. Edit the event registration through Blackbaud’s School Website System.
  6. Hyperlink text in the description to the video URL.

To embed through HTML:

<iframe width="560" height="315" src="VideoURL" frameborder="0" allowfullscreen></iframe>
The "VideoURL" will be the URL you get from the Video Content Category.

If you're using an external video from a site such as YouTube, you can click "Share" then "Embed" and take the iframe code provided here, and this will be your embed code you place in the HTML.
