You are able to add introductory videos to your template just as you would when adding a video to a created document. Since this is a template, however, we recommend using a standard video rather than a personal video to a specific person. For example, saying "Hey there!" instead of "Hi Mary..." to start the video.
When creating your template, you will see an Engage tab in the top right. Click on it and you will see a video preview with a Start button on it. Click this and your webcam will be activated. You will then be able to record a quick introduction video by clicking Record. Stop the recording by clicking the Record button again, then click Save:
To upload a standard YouTube video, a Vimeo URL, or a video stored anywhere on your computer, simply click the library button. Once uploaded, you can add it your library and decide to share it with your team.
