That is an awe-inspiring and highly educational video. I just had to watch it repeatedly, and then go back and replay certain parts. At the C2 point, the details of the lunar edge are amazing. I was surprised at first that you can't see the mountains of the Moon extend past the limb of the Sun, but it makes sense -- there is no light to show them once they pass that arc. After totality, once the aperture is changed to capture the corona, you can again see the irregularities in the lunar edge. Then, at the C3 point, as the Sun begins to emerge again, the diffraction in the light is really amazing and so beautiful.
I am not certain if this is an artifact, but I think I can see some variations in the corona as the video progresses. But with the camera motion and changes of settings, I cannot be at all certain about it. On this time scale, the prominences appear as frozen features.
