The developer said the following which makes sense but since this is integrated with Joomla and Gantry, I’m not sure how it correlates into the framework. Currently, I use g-features as the element ID and I put all my particles in this section because I want a background for the whole page. Perhaps not meant to do it that way. I couldn’t find how to put the video background on the whole page instead of sections. In Gantry, is there a body section that correlates to the element ID?
Did you try to set the “body” as containment of the YTPlayer?
Your video is blurry because is set as background of a very high container causing the inclusion of a really big iframe to fit the containment. The youtube iframe in your case is: 8901px x 5006.4px and the video definition is lower.
Setting the “body” as containment the max height would be the windows height and the iframe would be the right dimension.”
