Addictive video upsells or I riot

I can’t help but think there really should be a way to offer a different reward for video testimonials. Should be able to “upsell” another incentive if they add a video testimonial.

Right now you either give the reward or not. But you should be able to give a base reward for all testimonials, and show a “want the premium incentive? add a video” for videos.

Thoughts? Seems like it should already exist given the overall really good UX, not sure why it doesn’t.
