The first step in adding a video is clicking on the "Video" button:
You will then be presented with a few simple options: URL, Auto Play, & Progress bar.
URL: You can paste the URL of any YouTube, Vimeo or Wistia video into the form field.
Progress bar: With YouTube videos, you have the option to hide or show the bar at the bottom of the video. Removing it can add to the visual appeal of your video and keep watchers more focused.
Auto Play: This will force your video to start playing automatically. This feature is only recommended if the video is the primary focus of your landing page and if it does not have sound.
Note that the Auto play option will not work if the video has sound.
If your video is not hosted on YouTube, Vimeo, or Wistia, you can still add it to your page using the HTML element feature.
