Your argument relies on assumed position of the moon based on your best guess and the same for the sun which we do not see in the video. I do agree that your contentions are seemingly impossible if we assume what you've laid out in the op. But like markjo said, you've presented no evidence about where the sun is.
Please discover the definitions of dawn and dusk.
We know where the sun is when the moon is fully eclipsed... it's directly behind the earth, lined up with the earth and moon.
Excuses that the sun is "also" refracted 0.5 degrees into the air are meaningless when we see that the required angles of refraction must be significantly more than a 0.5 degrees here and there for any of this to occur.
Oh, so you don't think this video depicts a selenelion?
I'm not making excuses, I've been hammering on about all the things that you haven't considered before you drew your initial conclusions in the op. If the moon is as high as it is in the video and if the sun hasn't even risen yet until the moon is much closer to the horizon toward the end of the video, then I don't see the problem. Since there is no evidence of what is going on with the apparent position of the sun other than the fact that it looks like dawn, then what else can be said?
We don't need to know the position of the sun behind the camera for this.
When the moon is eclipsed we know that the sun, earth, and moon are completely aligned. At this moment in the video we can see that the moon is several moon-diameters above the horizon line. I estimate over 4.5 moon diameters with a ruler. Knowing that the moon takes up 0.5 degrees of the sky, we can compute (0.5 x 4.5) that moon is over 2.25 degrees above the horizon.
Thinking back to the scaled model; if it takes over 1 degree of refraction just to get the moon to the horizon, and it must take an additional 2.25 degrees to get into its position into the sky, the moon must therefore be refracted at least 3.25 degrees to be where it is.
This is ignoring that the moon must be even lower than the last scaled model I posted depicts, beneath the earth's shadow, to account for it being lit from the bottom up.
Altogether, we see that the scenario is plainly impossible.
