How to change zoom mode of a background html5 video? - css

<div class="mission-statement">
<video style="min-height:100%" playsinline autoplay muted loop poster="{{ url_for('static',filename='images/cclc-background-image.png') }}" id="bgvid">
<source src="{{ url_for('static',filename='videos/cclc-clip2.mov') }}" type="video/webm">
</video>
</div>
#mission-statement {
margin-top: 0px;
margin-bottom: auto;
height: 100vh;
width: 100vw;
}
video#bgvid
{width: 100%; height: 100%; position: relative;}
Currently I have a video in the background of this div. However currently, when the screen is really wide, there is space on the left and right and when it is really narrow, there is space on the top and bottom.
Instead, I would like the video to zoom such that it is always touching all 4 sides. If the browser is narrow, it will be zoomed such that the left and right parts of the video are cut off. If the browser is really wide, it will be zoomed such that the top and bottom are cut off.
How can I accomplish this?

If you are only concerned with real modern browsers that conform to W3C standards (i.e. Not IE), use object-fit:cover. If IE is a must, there's a polyfill, but other than that, it would take too much effort and time to force a "browser" like IE to conform when it's obvious design is to conflict with everything that's sane and logical.

Try this:
video#bgvid {
/* Make video to at least 100% wide and tall */
min-width: 100%;
min-height: 100%;
/* Setting width & height to auto prevents the browser from stretching or squishing the video */
width: auto;
height: auto;
/* Center the video */
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
}

Make fixed height of an video elment

I have a certain problem that I came across I need to make a video element with fixed height as well I have a canvas element that is positioned on top of the video element which represents a rectangle that is drawn across the object.
When I use object-fit with max-height: 60vh, the canvas element as well gets shrunk to 60vh but instead, it should be 100% height
.display-cover {
position: relative;
}
#video {
min-width: 100%;
object-fit: cover;
max-height: 60vh;
}
#camera-feedback {
position: absolute;
top: -30px;
left: 0;
right: 0;
bottom: 0;
width: 100%;
height: 100%;
}
<div class="display-cover">
<canvas id="camera-feedback"></canvas>
<div class="video-cover">
<video id="video" autoplay playsinline>
Your browser does not support the video tag.
</video>
</div>
</div>
Image example ( yellow rectangle should cover all document), when height of the video is 100% it works fine

prevent video with max-width jumping onload

I'm trying to precent a video from jumping when it loads, I have applied this aspect ratio padding trick which works fine, but not when the video requires a max-width, the padding applied seems too much and never fits correctly. Any ideas?

.video-wrap {
position: relative;
height: 0;
padding-top: calc(675 / 1200 * 100%);
}
#tutorial-video {
position: absolute;
top: 0;
left: 0;
max-width: 600px;
width:100%;
height: auto;
}
<div class="video-wrap">
<video id="tutorial-video" width="100%" poster="/assets/video-poster.jpg" autoplay loop playsinline>
<source src="/videos/tutorial.mp4" type="video/mp4">

Overflow: hidden for HTML5 Video

I am trying to hide the overflow of an HTML5 video that is wrapped in a container. However there are still scroll bars in firefox and chrome. When I try to recreate the issue in Jsfiddle, it works fine (no scrollbars), but the same code in firefox or chrome creates a scroll and does not hide any overflow.
Any idea how I can get the overflow of an HTML5 video to hide, and why it's not working? PS. I have tried changing the position of the container to various things and have tried breaking overflow: hidden down to overflow-x and overflow-y
<div class="video_container">
<video autoplay loop controls muted="true"class="video_window">
<source src="http://www.html5videoplayer.net/videos/toystory.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
</div>
CSS
.video_container{
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: -100;
overflow:hidden
}
video{
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
#media (min-aspect-ratio: 16/9) {
video {
height: 300%;
top: -100%;
}
}
#media (max-aspect-ratio: 16/9) {
video{
width: 300%;
left: -100%;
}
}
This one should do the trick if you meant those annoying bars with scroll element on your DIVs. Set this to your wrapper element (e.g. .video_container)
&::-webkit-scrollbar {
display: none;
}

How can I make an HTML5 Video popup to fit the center of any screen?

I want to make an html5 video fit any size of the screen, if it's a iMac huge screen or if it's a phone, I want it to be responsive.
1) If it's a 4:3 monitor, it should show blank spaces (black bars) above and below video
2) If it's a super wide screen it should fit the height but show blank spaces left and right
3) Same with mobile, if it's portrait or landscape position
This is my HTML
<div class="video-container"> <!-- background darkener -->
<video controls>
<source src="img/vid.mp4" type="video/mp4">
</video>
</div>
CSS:
.video-container {
position: fixed;
top: 0; left: 0;
width: 100%;
height: 100%;
background: rgba(0,0,0,0.9);
}
.video-container video {
/* Here is what I want to know how to make it fit the way we want */
}
I don't mind using jQuery if more real time calculations are needed!
Thanks beforehand
Try this, works for me
.video-container video {
position: absolute;
top:0;
right:0;
bottom: 0;
left: 0;
width: 100%;
height: 100%;
background-size: 100% 100%;
background-image: url('your-video-poster.jpg');
background-position: center center;
background-size: contain;
object-fit: cover;
z-index: 100;
}

Responsive Background Video

I am looking to make my video background like this:
http://www.teektak.com/
The issue I'm having is that my video is responsive, but it is fixed to the left. I can't figure out for the life of me how to make it so that it centers horizontally to the window when adjusted.
Here is a link to the test site to see what I am talking about: https://robotplaytime.paperplane.io/
HTML
<body>
<video poster="images/robotPlaytimeVideo.png" id="bgvid" autoplay loop muted>
<source src="images/robotPlaytimeVideo.mp4" type="video/mp4">
</video>
</body>
CSS
html,
body {
height: 100%;
width: 100%;
overflow: hidden;
}
video {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
min-width: 100%;
min-height: 100%;
z-index: -100;
background: url(../images/robotPlaytimeVideo.png) no-repeat;
background-size: cover;
}
Add these CSS rules to your body (the video's parent container):
text-align: center; /* ensures the image is always in the h-middle */
overflow: hidden; /* hide the cropped portion */
Add these CSS rules to your video:
display: inline-block;
position: relative; /* allows repositioning */
left: 100%; /* move the whole width of the image to the right */
margin-left: -200%; /* magic! */
Most of this was pulled directly from Bryce Hanscomb's answer to another similar question: How to center crop an image (<img>) in fluid width container
Here's a jsfiddle just in case:
http://jsfiddle.net/pLj0gcpu/
(Note that the markup and styles in this fiddle were pulled from your given URL)
To get the video to take the full size of the screen:
video {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
height: 100%;
width: 100%;
}
If you wanna center something horizontally responsively, then do
left: 50%;
transform: translateX(-50%);
Note, you will need to set a "position" as well
