Another option to upload a YouTube video would be to use the iFrame code provided by YouTube. This will allow you to customize the size of the media box that appears on the page. For example, this is the iFrame provided by YouTube for the video above:
<iframe width="560" height="315" src="https://www.youtube.com/embed/kbLE1-nOlSs" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
