Compared to the analog technologies we used in the nineties to create videotapes, digital video takes no time at all to create, because it's already digital as you shoot. The total cost of the equipment needed is zero, because all the equipment you need is already built into your laptop or even your phone. Upon discovering the principle of leverage, Archimedes said, "Give me a place to stand, and I can move the world." Digital video is one seriously big lever. Go move the world.
