when i set hover property on video. it doesn't reflect.

and i want to make a provision that after hovering the content in overlay header displays and disappears after 5 seconds.
can somebody help me with the css.
here is my html code 

```
<body>
  <div class="video-container">
    <div class="overlay-header"><h1>Joker</h1></div>
    <div class="video-wrapper">
      <video class="video" autoplay controls>
        <source src="../../assets/movies/joker.mp4" type="video/mp4" />
        Your browser does not support HTML5 video.
      </video>
