Video In Product Media: With Autoplay, Loop And Audio

[FedericaFD]

Hi,
I use the Iconic theme, I have embedded videos in some products in .mov format, which work, only clicking on it and it becomes a horrible thumbnail. I would like to have an autoplay video, that loops with audio and simply activates once it is in the foreground (scrolling through the photos)
I suppose I need some html code to put in my media.liquid, as I read in some English discussion from which I took inspiration by doing various tests (but they were using a dawn theme)
I attach screen
Thanks to anyone who will help me.
