It looks interesting enough, from what I skimmed through on the page.
However, you're 15 minute promotional video... I'm not sure that's a good idea. Maybe people who contribute to indiegogo's regularly are more likely to spend 15 minutes to watch your video? I don't know (but if people are surfing indiegogo looking for something they want to contribute to, my guess is they'll look at 5 three minute videos before they look at one 15 minute one). But it lost me. I went back up the page to watch it, but I don't really want to take those 15 minutes out of my day, as harsh or petty as that sounds. If your video was 5 or less minutes (preferably less) I would've watched it, and maybe donated.
That doesn't mean having all that info is bad, but it makes it hard to hook people. You could split the video into a series of videos (so one is a very basic hook, then the following ones go more in depth).
