Video does not solve the fundamental photographic problem, which is this: what is it that is worth photographing? Sure, use video and you may end up with a lucky shot now and then. (A couple of people have shown this to be possible, using the vast resources of Google street view.) But don't think indiscriminate shooting will be less work. Editing in particular will be a new form of torture.
If you know what you're after, a few shots will be as good as 72,000 frames. And if you don't, 7,200,000 will not be enough.
