How Do I Add A HTML5 Video Creative To An Existing Line Item?

Note: "MP4", "OGV" and "WEBM" are the names of video codec formats that are used in HTML5 video. For cross-browser support, you'll want to have the video hosted in all three formats. We cannot serve or transcode these videos at this time. Thus, the HTML5 medium is not for most customers and the YouTube creative template is highly advised instead.

"Autoplay," when set, starts the video automatically. "Controls," when set, enables the HTML5 video controls to be used. "Muted," when set, mutes the video by default. "Looping," when set, controls whether or not the videoplay loops on completion. "Destination" is the URL to which the video will click (when not clicked on the controls).
