Great looking site!
One thing I noticed was that I almost missed the fact that the pretty image in the center was a video because there was no "play" button visible. I just happened to click on the image & a video started playing.
It might be a good to have a triangle "play" icon on the video, or show the play/pause buttons at the bottom of the image. That could possibly reduce your bounce rate, which *might* increase your SEO. (There are mixed opinions about whether time spent on site helps with SEO, but it certainly can't hurt.)
