To place an in-line vimeo video player into your publication you'll need to create a HTML interactivity element and copy the code below:
<iframe src="http://player.vimeo.com/video/[VideoID]?title=0&byline=0&portrait=0"
width="100%" height="100%" frameborder="0" webkitAllowFullScreen
mozallowfullscreen allowFullScreen></iframe>
You'll need to replace the [VideoID] at the end of the url with the relating video id from your video.
