Help with custom code displaying a video

So I have this code that is displaying a video, but this was the placeholder from a clone.

so if this is the source how can I host my video the same way? Cloudfront links to amazon AWS but I don’t know how to host a video with them like this. Any help would be greatly appreciated!

Thank you!

Hopefully this displays, added a few spaces

< video playsinline="" loop="" muted="" id=“main-video” style=“max-height: 50vh; max-width: 100%; display: block; overflow: hidden; border-radius: 5px;” poster=“”>
< source src=“” type=“video/mp4” >
< /video >
