We've seen this great post about pulling stills from video before. It really opens up the discussion about what technology can do for us. Will video really replace photography? The reality is it probably won't. There are quite a few pros and cons that go along with it. The Slanted Lens goes in depth with this behind the scenes video with a Canon EOS-1DC.
I really felt this video was well done for people like me who know more about photography than videography. You clearly begin to realize the limitations that come with pulling frames from videos in many situations. This doesn't mean that it's entirely not possible but you can't have your pie and eat it too every time. As long as you well aware about the limitations, you can be better prepared to use this option to your advantage.
