Again, it's a poor example because the eclipse was only partial ("penumbral").
It seems to me that the first part of the video, showing a slowly growing ring
of light around the earth, wasn't due to the movement of the celestial bodies,
but just some shutter being opened.

That said, while only the ring was visible the HDR camera may have been
operating at a dynamic range where brightness could be discerned but not color.
