on my end here it starts auto and in lightbox: http://alsafahalal.com/al-safa-revamp/
Thanks for the response. It seems to work on internet explorer, but not on Safari. I am yet to try it on Chrome and Firefox.
Is there a way I can guarantee it autoplays on all browsers?
There is no guarantee, Safari has its own policy for the video autoplay. The video auto-plays in Chrome on a Mac.
Thanks for the help Victoria. I might just upload the video to YouTube instead.
