I tried doing an animation of an image in Premier Pro to put on Facebook - I did it the exact dimension Facebook said, but when I tried to upload it, it got rejected because the aspect ratio was wrong (it needed to be between 1:1 and 2:1 apparently). I googled about this and it seems you need to set up a sequence and set the pixel aspect ratio but when I did the 2:1 setting the video had black borders. How do I create a Facebook video (from an image) in Premier Pro? What settings do I use? Note there only seems to be a fixed set of aspect ratios to choose from and most of them were not between 1:1 and 2:1.
