Here is my half baked analysis. I was trying to prove that it was a Trident II being launch from a sub. I ended up disproving that. So it was more likely a missile flying horizontally south-bound from somewhere out of view. Unknown if this was a offensive missile targeting AF1 or if it was a second defensive missile shooting down the first (unseen).

I don't think there ever was a video. This is from a weather camera that takes stills and time-lapses.
