iPhone 6 Video Pulse Does anyone know what this strange effect is in my video?  It's almost as if something is causing the video to "pulse" and reset somehow.  At first, I thought perhaps my own heartbeat was causing a slight vibration resulting in this but the first video was taken with the phone on a stand:


                
            


                
            

You may have to watch kind of closely to see it but I think it's pretty pronounced in the grass, trees, and cherry blossoms at HD and full screen.

It seems like the video is alternating between sharp and soft so I guess it's just an artifact of the compression but I haven't noticed the effect being so bad in other videos.

Is there anything I can do to fix this?
It looks like its the iPhone auto focus, try finding an app that doesn't use the auto focus
