I’m gonna show you how to embed a Vine video from your phone to your wordpress post. It’s pretty easy.
First, click on the three dots in the bottom right hand corner of your post (pictured in the first image above). A screen will come up with some choices. Pick the “Share this post” selection (as pictured in the second image above) and then “Embed.” (OK, this part is a bit like Twitter.)
Finally, to display your Vine clip as a looping video rather than a video embedded in a player like a YouTube clip, you’ll want to copy just the URL minus the “/embed” shortcode on the embed page. Place that in a single line in the HTML of your page where you want it to appear.
