cell phone video with wings?

I see loads of videos with a video in the middle and an out of focus
partial video on each side of it. I've concluded that these are
cell-phone videos. Yes?

So how come none of my cellphone video was like this?

And, how come theirs are?

My cellphone video and photos were probably not as good as I got from a
real camera, even point and shoot, but they look pretty good and they
don't have blurry wings.
