Html5 video background, keep center of video in center

Question

I am trying to keep a background video centered regardless of how big the user drags the video. It\'s currently cutting off the right side of the videos when i scroll smalle

Answer 1

just center it like any other element with position absolute

.video_contain {
    position: absolute;
    width: auto;
    min-height: 100%;
    min-width: 100%;
    left: 50%;
    transform: translate(-50%);
}

Answer 2

This did the trick for me, keeping the video centered all the time and not worrying about the actual dimensions of the video

.video_contain {
  position: absolute;
  top: 0;
  left: 0;
  /** could be any size **/
  width: 100%;
  height: 100%;
  overflow: hidden;
  z-index: 0;
}
video {
  display: block;
  min-height: 100%;
  min-width: 100%;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  z-index: 1;
}

Answer 3

  .bg-video-wrap {
    position: absolute;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
  }

  .bg-video-wrap > video,
  .bg-video-wrap > iframe {
    object-fit: cover;
    object-position: center center;
    width: 100%;
    height: 100%;
  }

Answer 4

here's how I typically do background video, and how I did it for the stre.am landing page:

.video_contain {
    position: absolute;
    top: -50%;
    left: -50%;
    width: 200%;
    height: 200%;
}

video {
    position: absolute;
    top: 0;
    bottom: 0;
    right: 0;
    left: 0;
    margin: auto;
    min-height: 50%;
    min-width: 50%;
}

Answer 5

Late to the party but I wanted to give a 2020 answer. Here's a simple solution that lets you have an HTML video both centered and responsive without being "fixed" positioned. It lets you start with a fullscreen intro and add some text right when you start scrolling. No scrollbars, no annoying things. As simple as that.

CSS

* {
  box-sizing: border-box;
}
body, html {
  margin: 0;
  height: 100%;
  font-Family: Arial;
}

.video-container {
  display: grid;
  justify-items: center;
  align-items: center;
  position: relative;
  width: 100%;
  height: 100%;
  overflow: hidden;
}
.video-container video {
  position: absolute;
  z-index: 1;
  top: 50%;
  left:50%;
  min-width: 100%;
  min-height: 100%;
  transform: translateX(-50%) translateY(-50%);
}
.video-text {
  z-index: 2; 
  color: #fff;
  text-align: center;
}
.video-container h1, .video-container h2  {
  margin: 0;
  font-size: 3rem;
}
.video-container h2  {
  font-size: 1.4rem;
  font-weight: normal;
  opacity: 0.6;
}

.page-content {
  line-height: 1.4rem;
  padding: 2rem;
}

HTML

<div class="video-container">
  <video autoplay muted loop>
    <source src="https://www.w3schools.com/howto/rain.mp4" type="video/mp4">
  </video>
  <div class="video-text">
    <h1>Catchy title</h1>
    <h2>Everyone loves catchy titles</h2>
  </div>
</div>

<div class="page-content">
<h1>New paragaph</h1>
Some random text goes here...

This worked for me

.video_contain {
  position: absolute;
  z-index: -1;
  top: 0px;
  left: 0px;
  bottom: 0px;
  right: 0px;
  overflow: hidden;
  background-size: cover;
  background-repeat: no-repeat;
  background-position: 50% 50%;
  background-image: none;
}

#bgvid {
  margin: auto;
  position: absolute;
  z-index: -1;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  visibility: visible;
  width: 1267px;
  height: auto;
}
