You said you failed to connect with people on an emotional level, but I would contend that you failed to solve a problem perceived by the customer.
Only when you solve a customer's problem will you get that emotional connection. It's not something you need to work at, it's something you either succeed at doing, or fail. I would say that your application just didn't solve anything someone was looking for.
Your questions led you down the wrong path. Your very first questions should have been:
1) What is the pain point that X have?
2) How can I solve that with an iPhone app?
Where X is anybody you thought you were solving a problem for.
"Do people wake up in the morning and say to themselves, 'Holy crap, how am I going to save and share videos today?'"
I don't think they do, which is why this particular idea and implementation aren't going to gain any traction over what exists today. It's just not a strong enough pain point to be solved by an iPhone app.
If you stay in stealth mode for long periods of time prior to launch, the "amount of righteousness" in your vision/future-product and the conviction with which you believe this, will not help you overcome the impedance barrier of becoming part of the Internet zeitgeist.
Sometimes, you do not appreciate how deep the water is (nor how fast it flows) until you step into it.
My only question is why you feel that the answer to the most important question - "Is there any interest in this product in the market?" - is "Yes"? You've identified that they way you went about promoting and raising money could be improved, but assessing the biggest problem as one of promotion is not obvious.
