I agree that the video in the OP does have that sony look to it. But the motion looks a bit more unnatural than in other clips. What is the detail setting? On my FS100, I'm now convinced -4 or lower is the way to go to achieve more natural motion.
That's interesting as I'm just learning the FS700 right now. But what you are saying is that by lowering the detail, you get a smoother motion? How does that work technically?
