Can you autoplay vimeo video from an input in a collection?

I’m displaying a projects as part of a company portfolio.

At the top of each page is a video. The project template has a collection where the video input is linked to. The videos are coming from Vimeo.

I’d like have these videos autoplay, I can’t seem to get anything to work I’ve already seen on the forum. Does this kind of thing only work when you’re using an iframe and not from a collection?
