I have to say this is pretty genius. This could take e-cards to a whole new level. Suggestions: some of the text is impossible to read - I had to guess what the registration form fields were. But the rest of the design is nice. Also it's slow. I know you're doing video rendering, but if you could find a way to cut down the render time, you'll probably up your retention and repeat rates. Also you want to be able to add a longer message at the end of the video: the video is the "front" of the card, the end message the contents. Plus get your cost down to a dollar.
