This is not an arbitrary dictate by Facebook. It is realistic. For most of our video presentations, the receiving device will be a Smartphone, held in the portrait position. That is the position that nearly all Facebook users hold the iPhone when scrolling through Facebook.
The video marketer must then grab the attention of the Facebook scroller, so that they will stop and actually watch the video. The most perfect display is 5 x 4, because it automatically users most of the iPhone display, the phone does not need to be rotated, so that the user will automatically see the great opening display. And then watch the video.
16 x 9 may look great when the phone is rotated, but quick scrollers will not take the time to rotate the phone. They will instead keep on scrolling, right past the otherwise great video you created.
Please add variable aspect ratios. If not variable, then specifically add 5 x 4.
Watch this video to see.
