In ONTRApages and ONTRAforms, you can autoplay videos when using Wistia, Vimeo, YouTube or ONTRAPORT hosted videos.
You can also set the thumbnail or title slide on the videos when using Wistia, Vimeo, YouTube and ONTRAPORT-hosted videos. Wisita and Vimeo videos use their Admin settings (in their application) to control this, and the embed code simply calls that configuration. For YouTube and ONTRAPORT hosted videos, you can use the following steps to enable autoplay and set the title slide (thumbnail).
For ONTRAPORT hosted videos, first select the video on the Hosted tab from the drop down box. This box will have all the videos you have uploaded into the Video Manager in ONTRAPORT. Allow the video to load in the Canvas, then click the "Embedded" tab. Note that ONTRAPORT uses HTML5 for the embedding; simply add the HTML5 tags you want to control the video.

YouTube videos can be set to autoplay following these directions from https://support.google.com/youtube/an...:
*To make an embedded video autoplay, add "&autoplay=1" to the video’s embed code right after the video ID (the series of letters that follows "v/"). Embedded videos that are autoplayed don't increment video views.
Example:
<object height="350" width="425"><param name="movie" value="http://www.youtube.com/v/OdT9z-JjtJk&autoplay=1" /><embed height="350" src="http://www.youtube.com/v/OdT9z-JjtJk&autoplay=1" type="application/x-shockwave-flash" width="425"></embed></object>*
