I didn't see anything wrong with the headline. But if this is a landing page, it's missing the opt-in box to capture your visitor's information.
Also, and that's just me ... the video is more of a tutorial for the system (and quite long.) Most people might not be patient enough to sit through it as we're all very busy. Especially since it doesn't show how long it will be.
I think for a landing page where you capture the information of your visitors it would be better if it was "Short & Sweet" and then give them more information later. When people first come to your page they don't know anything about your product and they may get overwhelmed with all the info in the tutorial.
Okay after about 18 minutes in the "purchase button" came up.
Tell you the truth, if I just landed on your page without you asking for feedback, I wouldn't have stayed around long enough to see that button.
Just my thoughts
