Reseting the background video after slide switching

With the combination of our  javascript code and some jQuery code, you could insert this:

var sliderID = 4;
n2ss.ready(sliderID, function(slider, sliderElement) {
    sliderElement.on('mainAnimationComplete', 
    function(e, animation, previousSlideIndex, currentSlideIndex) {     
	jQuery('#n2-ss-' + sliderID).find('video')[0].currentTime = 0;
    });
});

into the Javascript callbacks of your slider or any place, where that javascript code would be triggered. At the sliderID variable replace the number 4 with your slider's ID, and this code will reset your video to 0 second after a slide change.
