I was hoping to get started on this today, but I must say, I'm incredibly confused now.
I was picturing a small ad that would appear at the side or the bottom of the screen.. But based no the specs you have provided, it sounds like you're looking for a full screen video.
Is there any chance you could provide me with a link to an example facebook ad? Or do I just need to turn off my adblocker and go to facebook?>
Your first impression was right. It is small. I only included the info on animated gif ones because you asked. There is an example in the post of what one looks like.
