Yep, froot-loopery of the worse kind. There are three enormous holes in his explanation.

1. The vanishing point. If the Earth really is flat, the vanishing point of the observer's point of view is at the observer's eye height above the ground. If the observer is six feet tall, the vanishing point is six feet above ground level. If the observer is on top of a 10,000 foot mountain, the vanishing point is 10,000 feet above ground level. The video shows the sun BELOW his vanishing point (6pm), something that he himself implies is impossible, then he ignores the fact that his diagram shows exactly that.

2. The apparent diameter of the Sun. If the Earth really is flat, and the sun really is 3,000 miles above the surface and travels parallel to the Earth's surface, then it would appear to get smaller as it got further away from the observer. The difference would be dramatic - at twice the distance, the Sun would be half the apparent size it is overhead. By the time the Sun reached the horizon, it would appear little more than a small spot of bright light.

3. Relative angular velocity of the Sun. The Sun tracks across the sky at a rate of 1 every 4 min (15/hr). This is an undeniable, observable fact. Taking the starting point as the Sun overhead the observer, if the Sun was travelling at a constant speed on a flat Earth, it would appear to get slower and slower as it approached the horizon. The only way to reconcile this with the ob served facts is for the Sun to accelerate as it approaches the horizon.... and it would never get there because in order to do so, it speed would need to reach infinity.
