What would you want in an auto-generated product demo video?

I’m building ClickCast, a tool that turns a website URL into a cinematic product demo video.

Right now it works best with public pages (landing pages, onboarding flows, marketing sites), and we’re opening early access to learn from real users.

I’d love to hear from founders, marketers, and builders here:

• What makes a product demo video actually useful for you?
• Do you care more about speed, polish, or customization?
• Where do existing demo tools fall short?

Any insights or feedback would directly shape what we build next.
