A background video or 'hero' video can be found on many webpages to enhance the visual appearance of the content. They usually appear at the top of the page, but could be located anywhere where an inline 'video loop' makes sense.
Vidyard's embed codes are primarily suited to show a player with controls such as play and pause, but a background video is designed to continue to loop with no audio and ideally not send analytics.
The solution is to use a custom iframe code for this type of experience (currently not shown in the Vidyard UI).
Use the following code, replacing UUID with the valid UUID of your video:
<iframe src="//play.vidyard.com/UUID/type/background?preview=1" scrolling="no" frameborder="0" allowtransparency="true" allowfullscreen="true"></iframe>
