How to embed a video file for a website so that it loops?

Question

Does anyone know how to embed a video image (about 5 seconds long) for HTML so that the video image can look by itself on a webpage?

Answer 1

You should do it like this:
<video autoplay loop>
<source ... >
</video>

Answer 2

And for the source and video would I just add the URL? Another question, what if its a video recorded on an iPhone? How can I extract that source to put it into the code?
