In regards to the height of the field barrier looking higher than normal:
It is a result of a weird camera angle.
I did an approximation of the the height of the barrier based on the length of the vertical section and the width of the tubing as seen in the video. I think that the tubing in previous years is 2" in diameter (someone can correct me on that).
With that assumption, the height of what is shown is 20.8". There is a little bit cut off by the edge of the screen, but this demonstrates that there won't be much deviation from the 20" that we are familiar with.
Frankly, I'm saddened that someone else didn't already figure this out. Simple math.
