Take a look at this one.
If some Weblow Pro can give a suggestions, how to:
1. Full Screen Video, transitions (slides), etc.
2. After I push the play button and see the trailer, and then close it - the button changes to "Be the first to see it" and "Watch again"
3. Of course, this amazing "Enter your mail" in the bottom of scroll, with the letters collecting accorsing mouse move.
Great design, isn't it?
