auto HD & fit to screen

Hi,
For hd by default you need to edit this file:
plugin_folder/js/mag-popup.js
find the text
https://www.youtube.com/embed/%id%?autoplay=1&rel=0
and make it
https://www.youtube.com/embed/%id%?autoplay=1&rel=0&hd=1

The black box isn’t a separate thing. It’s the thumb image generated by youtube.

previous links automatically included https://
just look for
https://www.youtube.com/embed/%id%?autoplay=1&rel=0
and make it
https://www.youtube.com/embed/%id%?autoplay=1&rel=0&hd=1

BTW, the api doc says HD parameter is deprecated.

Marking as resolved
