Length of Video in Revolution Slider

I have a placed a video as the third slide in the Revolution Slider. I want the slide to continue until end of video and then transition to next (4th) slide. I selected “NExt Slide on End” but it only plays quick part of youtube video and then shows text I have over video. It then continues to next slide. How do I get the revolution slider to not slide until end of video? My site is: http://www.miamimxparksupport.com

I love your theme btw. really amazing what the Highend theme can do.
