The Problem

The slider has a max-height of 570px, so using an HD video with the centered layout is not really ideal. We allow the height to flow below the slider to achieve the parallax effect on images like the iphone app preview image seen on the demo etc

The Solution

You can either increase the height of the slider (not recommended as this affects all slides), change the layout to right-aligned,  or add this to the Custom CSS of Theme Options to constrain the video:

.slider .image-title .slider-image{max-width: 640px;}

.slider .has-video iframe{max-width: 640px; max-height: 360px;}
