Hi @Holly1
Thanks for posting.
I took a look at your project but I’m not sure what page or section the video is on.
That said, the issue could be related to another similar thread — please check out my reply here: Webflow video & loop issue - #2 by Brando
It’s also worth mentioning that autoplay specifically can be tricky to implement as Chrome changed the policy around autoplaying videos (see full details here).
