Let me start by saying that I can see a real difference between 24fps, 30fps, 60fps and 144fps on a 144hz monitor (we don't have to start that discussion here). Sure it's a nice thing that the iPhone 7 can record in 1080p in 120fps and all with the slo-motion. My only concern is that it doesn't make sense any other than the slo-mo feature. I don't see the point in filming in any higher frames than 60. None of the iPhones or Macs even support a higher than 60hz screen refresh rate. No one will notice the difference between 60fps and 240fps because of that. Am I missing something here? Can some explain this to me please?
