I think screenshots could work as well, as long as you show what matters the most. Either way, you gotta make sure what you show doesn't make user feel overwhelmed. Too much text is overwhelming, too much screenshot or video do the same.

For the title, I don't see "straight from your web application" as a strong value proposition there. But might be because I'm not your ideal customer. The rest of it feels natural and easy to understand. Good job Marco! 👏🏻
