Keep asking great questions and focusing on fixing the issues and you'll get there! Video needs some innovation to become more accessible - you're on an interesting path!

Upon visiting the site - I'm not surprised that this is an issue. You are doing very little to illustrate how your product delivers value - and oddly, there is no explainer video - which for a company that produces marketing video, seems like not only an obvious move, but a requirement.

You need to go beyond benefits and talk about the value, but also tie it to how you create it.

Not suggesting any of the below as actual copy - just illustrating:

"The marketing value of video is huge - but producing video is time consuming and expensive. We've made it easy by producing the video for you - all you have to do is pick the one you want, add text, a logo, and your call-to-action and you've got a ready-to-upload video in minutes."

I'm sure you can improve upon the wording - and I may be off on exactly how it works (since we've agreed that the site isn't telling us that) - but I think you can greatly improve conversion and interest in the product with something similar.

If you'd like to walk me through the product I'd be happy to provide more specific feedback once armed with the facts.
