Video rendering suggestion
You should make the final frame in the video something better than just a screen full of legalese -- I just uploaded a video to facebook, and it appears to use the last frame as the default thumbnail. Ain't nobody gonna want to click on that!
Facebook might allow you to set or change the thumbnail somewhere on the video post. I'm pretty sure I've seen some people share where the thumbnail isn't that. Not exactly sure though. That being said, a good note to pass along!
