Bad video quality when slider starts
can you please help me to resolve problem with bad video quality when background video starts?
I am using revolution slider where is video background layer.
The video source supports 4K resolution: https://www.youtube.com/watch?v=ncZ9LpMDIi0&ab_channel=TJPup%C3%A1sek%2Cz.s.
On every start, my homepage video is blurred.
Is there some problem with the optimization which blocks proper loading of scripts?
My goal is to have video loaded in 1080p HD when it starts.
