</video>

As @zmehboob said, you will have to make a list of videos to pick one randomly.

For this purpose, I'm using an object that contains the different available types for creating source elements, then I pick a random one for src before iterating through its extensions for source elements.

Here is some code (Vanilla):

 // first create the list with extensions as parameters var videoList = { 'http://media.w3.org/2010/05/sintel/trailer': ['mp4', 'ogv'], 'http://media.w3.org/2010/05/bunny/movie': ['mp4', 'ogv'] }; function create_BG_Video() { //create the video element and its source var el = document.createElement('video'); var source = document.createElement('source'); // here is the magic that takes a random key in videoList object var k = randomKey(videoList); //iterate through each extension to make a new source type for (m in videoList[k]) { source.src = k + '.' + videoList[k][m]; var type; //as ogg video may be with a '.ogv' extension, we have to watch for it (videoList[k][m] == 'ogv') ? type = 'ogg': type = videoList[k][m]; source.type = "video/" + type; el.appendChild(source); } el.className = 'bg_video'; el.width = window.innerWidth; el.height = window.innerHeight; el.setAttribute('autoplay', 'true'); //Set it as the first element in our body document.body.insertBefore(el, document.body.childNodes[0]); } // if it is the only used instance, it could be placed at start of the function var randomKey = function(obj) { // Get all the keys in obj (here videoList) var k = Object.keys(obj) // Here '<< 0' is equivalent to Math.floor() return k[k.length * Math.random() << 0]; }; window.onload = create_BG_Video; 

 html, body { margin: 0; width: 100%; height: 100%; } .bg_video { height: 100%; width: 100%; margin: 0; top: 0; position: fixed; z-index: -999; background: #000; } #content { margin-top: 15%; color: #FFF; } 

 <div id='content'> <p>Well, the way they make shows is, they make one show. That show's called a pilot. Then they show that show to the people who make shows, and on the strength of that one show they decide if they're going to make more shows. Some pilots get picked and become television programs. Some don't, become nothing. She starred in one of the ones that became nothing.</p> <img src="http://lorempixel.com/300/200" /> </div>

So basically you'll want to run the function at pageload (wrap it in document.ready).

You will want a srcsList array which will hold all your video sources (don't include the file extension).

You want to select a random number limited by the number of sources you have.

Finally you will update the src for your mp4 and webm sources so they reference the new random src.

var srcsList = ["/templates/smartone/images/video/fondo1", "/templates/smartone/images/video/fondo2", "/templates/smartone/images/video/fondo3"];
var randomInt = Math.floor(Math.random() * srcsList.length);
var randomSrc = srcsList[randomInt];
$('[type="video/mp4"]').attr('src', randomSrc + '.mp4');
$('[type="video/webm"]').attr('src', randomSrc + '.webm');
