1136 means adding 88 screen pixels, which is 44 x 2.

44 is a magic number in iOS development. All navigation bars are 44px tall. All tap targets are recommended to be at least this size. It's very easy for developers to conceptualize 88 more vertical pixels and what to do with them; much easier to work with.

And let's face it, iOS is about the apps over watching videos. I'm sure 16:9 videos will look great.
