Video background not autoplaying

I purchased a template with a video background:
https://videographer.webflow.io/

but this template in my site just not autoplay the video:
https://hyper-human.webflow.io/
Tested on 3 different browsers (mac)

I found a solution in a topic: disabling “Reduce Motion” in accesibility preferences fixes it but i dont think this must be a real solution because the video on the template live preview works fine

Anyone knows if there is a solution to this?
Thnx in advance
