This might be helpful For reference: https://jsfiddle.net/gyx94wqj/

<div class="video-size">
    <video  autoplay loop controls muted>
      <source src="http://techslides.com/demos/sample-videos/small.mp4" type="video/mp4">
   </video>
</div>

.video-size {
    height:400px;
    width:100%;
    overflow:hidden;
}
.video-size > video {
    min-width: 100%;
    min-height: 100%;
}

Solution 3:

This is not possible because this css will technically stretch the video which is not possible.

You can change the size of video but only with aspect ratio. If you forcefully change the height it will leave blank spaces at top and bottom.

.video-size video
{
  width: 100%;
  height: 800px;
}

I have given height to video forcefully and see the example with black spaces : https://jsfiddle.net/ohk8w0s0/

I think you can use like below.

    .video-size
{
  width: 100%;
  height: 400px;
}
.video-size video{
  width:100%;
  height:100%
}

Solution 5:

.video-size
{
  width: auto;
  height: 400px;
}
