My embed code:

<iframe src='//player.vimeo.com/video/"+vid_id+"?autoplay=1' width='600' height='371' frameborder='0' webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>

where vid_id is pulled from the Vimeo API.

Vimeo provided embed code:

<iframe src="//player.vimeo.com/video/76883031?color=f0000c" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe> <p><a href="http://vimeo.com/76883031">Suburban Scum (Full Set)</a> from <a href="http://vimeo.com/hate5six">hate5six</a> on <a href="https://vimeo.com">Vimeo</a>.</p>
