```
<video id="vid" controls>
   <source src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/222579/twitter_cat.mp4"  type="video/mp4">
</video>
<script>
    window.onload=()=>{
        const vid= document.getElementById("vid");
        vid.currentTime=4;
        vid.playbackRate=-0.5;
        vid.play();
    }

</script>

```

I tried that but it didn't work, is there a way to play backward videos?
