The quality "seems" poor because its an embed from FACEBOOK.
Perhaps this link provides a better look at the video?

I started The Original iPhone Film Festival when the iPhone4 was released. We have been featuring films and supporting a growing iPhone Film Maker community since 2011. The guys at Filmic are good friends of ours and solid guys. As we have been saying for over 4 years...you have a film studio in your pocket ..what are waiting for? It's always been about the story...not just the tools. I used to shoot on Mini DV when that was the newest technology...my iPhone crushes that image quality now of course....just a thought.
