unable to locate special element for video

Solved except last query
Can someone help me locate the special element to place the video on my site - url - 108.179.232.164/~lounge3/addon/e2e/

I can hear the sound of video but can't see the the video yet. but if I change the z index to 1 from 0 i can see the video. Trying to find where to change the z-index to 1. I can see that when i inspect via firebug.

any help?

This is the code where i need to change the z-index =

<div class="mbYTP_wrapper" id="wrapper_mbYTP_JUXbgndVideo" style="position: absolute; z-index: 0; min-width: 100%; min-height: 100%; left: 0px; top: 0px; overflow: hidden; opacity: 1; transition-property: opacity; transition-duration: 2000ms;"><iframe width="640" height="360" frameborder="0" id="mbYTP_JUXbgndVideo" class="playerBox" style="position: absolute; z-index: 0; width: 1255px; height: 906px; top: 0px; left: 0px; overflow: hidden; opacity: 1; margin-top: -128px; margin-left: -302.5px;" allowfullscreen="1" title="YouTube video player" src=""></iframe><div style="position: absolute; top: 0px; left: 0px; width: 100%; height: 100%;" class="YTPOverlay"></div></div>

any chance you can help me to change the background color from black to white. See when the video runs there is a black top and bottom strip there, i want it to change to grey or white color. any help?

Hi 100khz
Thanks for contacting us and choosing our product!
Want to change color
Please go to JUX Background Video module -> tab Module -> Overlay Color: Select your desired color
Please refer to our documents. maybe it will help you. Thanks
docs.joomlaux.com/extensions/jux_bg_video/

overlay does not help to change the black lines on top and bottom of the video when the video is smaller than the module space. I tried overlay settings it does not effect the top and bottom black strips. If the video is placed in a module which is not of 16:4 aspect ratio, black bars show on top and bottom

HI 100khz,
I do not see the black line as you say. you can capture the image. I just saw a video of the run line. If you want to change that line.
Please enter JUX Background Video module-> Tab advanced Options -> Config custom CSS
add css
.mb_YTVPLoaded{
background: red;
}
If that is not the problem you need. please describe in more detail. Thanks
