What we learned from working with vertical video on Facebook
Sebastian Vega

That example where you used square video and put the text underneath is awesome. This technique helped move people from horizontal to square on Facebook this year. I think we’re slowly we are moving to more vertical content oriented world. When you talked about the different sizes on Facebook not displaying properly, I believe it’s because it changes it to a 1080 x 1350 viewing experience. I’ve had this trouble uploading vertical vlogs to Instagram since they cut off a lot and learned the hard way :P. They talk about it in their recommended size to upload: https://www.facebook.com/help/instagram/1631821640426723

Great write up!
