Hi WPMUDEV, hope all is good .

Can you help me with general Wordpress queries? Is so, please could you help me with this question.

What is the best way to get a full width video to display in the header of a homepage on a WP site?

I'm looking at using this theme - http://www.tfingi.com/ - or this theme - http://positivus-theme.com/ - for a client job, but need to display a full width header video in place of the static image on the home page.

Could you suggest the best way of doing this please? Happy to look at plugins or some custom coding in the child theme. Or whatever you think might be the best approach.

Thanks WPMUDEV. If you need any further info from me, please let me know.

Mark.
