Well, as counter-intuitive as it sounds, `muted` tag is somehow ignored; check out the snippet below,
first one is rendered with react, the second one regular html; inspect them with your dev tools, and you see the react on **doesn't** have `muted` attribute; I already tried `muted={true}`, `muted="true"` but non is working.

```js
function VideoPreview() {
  return (
    <div className="videopreview-container">
      React tag:
      <video
        className="videopreview-container_video"
        width="320"
        height="240"
        controls
        autoPlay
        muted
      >
        <source src="https://raw.githubusercontent.com/rpsthecoder/h/gh-pages/OSRO-animation.mp4" type="video/mp4" />
        Your browser does not support the video tag.
      </video>
    </div>
  );
}

ReactDOM.render(<VideoPreview />, root)
```

```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>

<div id="root"></div>

<hr/>
Regular html:
<video
  width="320"
  height="240"
  controls
  autoplay
  muted
>
  <source src="https://raw.githubusercontent.com/rpsthecoder/h/gh-pages/OSRO-animation.mp4" type="video/mp4" />
  Your browser does not support the video tag.
</video>
