How to apply a white “filter” (alpha 50%) on a HTML <video> tag?

I am looking for a way to add a "white filter" on top of a HTML , i.e. basically I want the video to look like being being below a white layer of 50% alpha.

I checkout the css filter solution but it does not provider unicolor option, any idea?

<video
poster="/assets/img/stuff.png"
autoplay muted loop
id="background-video">
<source src="/assets/video/stuff.mp4" type="video/mp4">

margin: 0;
border: 0;

#video_container
width: 480px;
height: 270px;
position: relative;
z-index: 0;

video
position: absolute;
width: 100%;
height: 100%;
background-color: royalblue;
z-index: 0;

#overlay
position: absolute;
width: 100%;
height: 100%;
background-color: rgba(255, 255, 255, 0.5);
z-index: 1;


<div id="video_container">
<div id="overlay"></div>
<video
poster="/assets/img/stuff.png"
autoplay muted loop
id="background-video">

The solution is:

<div class="overlay">
<video
poster="/assets/img/stuff.png"
autoplay muted loop
id="background-video">
<source src="/assets/video/stuff.mp4" type="video/mp4">
Your browser does not support HTML5 video.
</video>
</div>


With

.overlay
z-index: 2;
background: white;
opacity: 0.5;
