Hi ayyoub,
Thanks for contacting us and choosing our product!
About your question with jux background video you can don't worry about video on youtube server because if your video passed all rules of youtube.
The second question about video on local. In old version 1.x we have options to display video from local. However on version 2.x we removed it because it load very slow. So if you really need it please submit a ticket at member area. I'll send it for you!
Thank you for sending the earlier version of JUX background video. Still the local video doesn't play on mobile devices. I tried iPhone 5 safari and Chrome. It displays the background image instead.
Hi ayyoub,

But as our description about product. Background video don't work on mobile devices and it will use an image as background.
