Getting a full-screen HTML5 Video Background Blur to work?

Would this pen fit your needs?

HTML

<div id="container">
    <video id="videobcg" preload="auto" autoplay="true" loop="loop" muted="muted" volume="0">
    <source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/mp4">
    Sorry, your browser does not support HTML5 video.
    </video>
</div>

CSS

#container {
  width: 640px;
  height: 360px;
  overflow: hidden;
  -webkit-filter: blur(15px);
  -moz-filter: blur(15px);
  -o-filter: blur(15px);
  -ms-filter: blur(15px);
  filter: blur(15px);
}

#videobcg {
  width: 100%;
  height: auto;
}

You might want to make that video bigger than the parent and center it inside it, I think that would get rid of that white blur inside the borders of the parent.

@Ashugeo, I took your code and did what you suggested years ago and it seems to work.

Unfortunately, this doesn't seem to work. I also tried making the video even bigger and centering it, still doesn't seem to work.

@Finn C, Nowadays it seems to work using transform: https://jsfiddle.net/Erik_J/6f483wm9/
