You mean that you want to place some texts images etc. on the background's video ?
If you mean something like this , you can do it by positioning your div's .
Something like this :
<div class="video_bg"><iframe src="//player.vimeo.com/video/71906867" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe><p class="text">Some text goes here</p></div>
.video_bg iframe{
width: 500px;
height:281px;
position: relative;
}
.text {
position:absolute;
font-size: 20px;
text-align:center;
}
