It would have to be reproducible: one second of a snippet of a video clip of something; the next, the thing happening. You rewind it and play again. Scrub through and try to determine a different branch. At one timestamp, separation, peace, unknowing. In the next, flames and smoke and a flashing blur.

But no--the state of the world in that second versus the next could not have been predicted. It just happened, just so, and it would take longer to calculate the determinism than to adjust to the new.
