Video slides revolution slider

Hi I am simply trying to have 6 short videos (4 seconds)appear one after another with a fade. What is the difference between setting an HTML video as a slide versus a layer? I have the videos as slides but then don’t advance. The first one plays then stops and goes to black screen .The videos are hosted. NEXT SLIDE ON END is set to ON. LOOP is set to off. Cant get it to advance…: https://www.turnkindnesson.org/newtko2/slidertest/ thanks
