 * Hi, I tried to set the opacity to 0.0 and everything inbetween – however it did
   not work out, the caption was showed without opacity.
    What do I have to change??

 * Hi katrin, If you are using opacity for background then in caption background
   write
    rgba(9,9,9,0.5) for black color with opacity 50%

 * Hi,
    thank you, I have the option ‘Caption Background Color’. When I write rgba(
   9,9,9,0.5) there, the background turns dark blue but not opaque…

   effect
