I stand corrected on one thing. One good thing that I just learned (actually I learned 2 things when testing on the XT2).
1st, put the camera focus mode in C but use the single point focus point, not the multi-focus point. Then when you press the video record button, you can use the joystick to move the single focus point around and the continuous auto focus will follow that single focus point. So you can change focus point/location while recording video!! I did not know that!
2nd ... when the camera is in focus mode M (or the lens is in manual focus mode) you still get focus assist while recording video. I think on the XT1 there was no focus assist while recording video. So manual focus while recording video is much easier now.
