Video will not play on iphone

I have a hero video that I want to play on the iphone.

I’ve tried several things to get it to work. So far no luck. I’ve used mp4, mpeg4, mov videos. i’ve used videos that I know for a fact play on an iphone because i’ve used it on other sites without issue. i’ve tried to embed myself using html and not using the theme. nothing will get it to play on an iphone. Does anyone know how to get around this issue?
