Venture Capitalists are brainless, visionless bankers. They will invest money if it looks/behaves like something else that has already made money.
Business plans? they are a dime a dozen. There are companies that will produce an incredible business plan for you, and with the better business plan companies, you won't even have to answer too many questions - they will do the research and produce the projections for you. And it will be "VC Ready".
If I was in your shoes, I wouldn't even try to sell this to VC's. I would first create and expose an API for content companies to pass their clips through, charging a few cents per 100 frames, and returning to them an improved version of their clips. Now suddenly you have a product, and you can start offering this product to web sites that accept clips from users. Score one or two such customers, and your business plan people have incredible stuff to work with to make your business plans look extremely appetizing.
And if you decide you do want to do that API thing and turn your technology into a product, I can help you guys. Just contact me here
