To create a video autoplay, we would need to use Section > Embed
Using a YouTube video as an example, take the embed code instead of the share URL link.
In the example code below, add &autoplay=1 before the ending double quotes in the URL:
Original
<iframe width="560" height="315"
src="https://www.youtube.com/embed/D6Ac5JpCHmI?"frameborder="0"
allowfullscreen></iframe>
Autoplay
<iframe width="560" height="315"
src="https://www.youtube.com/embed/D6Ac5JpCHmI?&autoplay=1"frameborder="0"
allowfullscreen></iframe>
Then, add the embed code and click save.
