Hi Vlad, many thanks for your input, truth is I’m quite confused over here.
I will try your Live Composer recommendation on Sydney Pro (on a new page) and see how it goes. If not happy I’ll get back to you via this post to see if a switch to West Pro (which as you wrote “works with LC out of the box”) would be what I need.
Regarding your latest post, Crelly solution sounds good, however, it’s not there now, I do not know when it will be (last updated 7 months ago) and I’m trying to launch my site with Video Backgrounds ASAP.
What I also don’t know is in which respect a Video Background option plus a Video Header Option for Sydney Pro will overload the theme (?).
I’ve been using a free plugin for Background Videos with Sydney Pro, called “mb.YTPlayer for background videos” but it doesn’t offer an Image Fallback for iOS / Mobile devices etc. and it doesn’t provide timely support. And, as I’m no dev but rather a WP enthusiast, learning WP on the way by trial and error, this doesn’t help me really and delays me from launching my site.
Many thanks for your understanding.
