Can video be used in the background of Maranatha’s homepage?

Yes, it is possible to show a video in the background of the first section on the Maranatha theme’s homepage. This feature was added in version 1.4 of the theme (November, 2016). Make sure you are running at least that version then see the Maranatha homepage guide’s Video Background section for how to use this feature.
