Here's my take. As others have stated VC's are in this for money, thus you show them the business case and that incudes explaining the barrier to entry - why another 2 bright guys, suitably funded couldn't easily reproduce your efforts. Now my real advice is this: VC's are not interested in small play's, they want to put a significant chunk of money in, and take a large multiple on that back. What that means is they are interested in large $$ opportunities that may take some time to come to fruition ...and that involves plenty things that can go wrong along the way leaving you with nothing to show for it. You are 2 guys, you already have something you think is very impressive to show, you don't really need lots of capital to continue development, it's really just your time. Go shop this to the incumbents in the applicable spaces looking for an immediate sale, Adobe/Apple in authoring S/W, google/vimeo on the backend, go-pro/contour/canon/nikon etc etc on the consumer H/W side. What you are looking for is enough money for the 2 of you to have a nice 7 figure bank balance..which means sell it, go work for the buyer for a while, take the money now whilst there is no obvious competition or the market changes and minimize the risk. Don't hold out to be a bizzilionaire, the chances not matter how good it is are vanishingly small.
