    I know the 6s can record in 4k but can it playback in 4k? Will a video shot on the 6 look any different than the 6s? Wouldnt you need a 4k tv to really reap the benefits?

    Short answer is no. The iPhone screen is only 1080p on the Plus, slightly less on the regular. So viewing on the iPhone it self should not look much if any different than it does now. In order to fully enjoy that 4K video you would need a 4K TV or 5K iMac or the new 4K 21.5in iMac coming later this year. Both the 13in and 15in MBP will take partial advantage of it as they are higher than 1080p, but they are also not 4K only 2.5ishK.

    I was thinking this. But when you look at ppi the 6s about the same so would you actually see a difference between the phone and a 4K tv. Or am I just talking nonsense. Please correct me if I'm wrong haha

    PPI doesn't have anything to do with the 4k aspect. It might be super crispy on the 6s+, but you are still watching it in 1080p. Only way to see the 4k video in 4k is to watch it on a 4k display.

    PPI is different than resolution. So at 5.5in the PPI is about the same as the PPI on some 4K TVs but its not 4K. Its kind of how 1080p on the iPhone looks amazing but 1080p on a 70in tv viewed at around the same distance as an iPhone looks blurry because you can see the pixels when you are close enough. But 4K has 4 pixels for every 1 compared to 1080p giving you that higher resolution, clarity and definition.

    Now, even if the iPhone had 4k the screen it would not seem that much better because of Retina. The philosophy of retina is having a PPI so tight that they human eye can not tell the difference between pixels at the normal viewing distance. So adding even more pixels when your eye cant tell the difference starts to be a moot point. But with larger display you start to add definition. and that's were 4k really shines.

    Pretty much what everyone else said but I will add that you might as well record in 4K since you will most likely will keep the videos for years and most all of us will 4K or greater displays and tvs within 5 years.

    My only question is what will look better, 4K at 30fps or 1080p at 60fps. 60fps are just silly smooth videos, not sure if I could go back to 30 but we will find out in a couple weeks.

    If you have a 4K TV 4K at 30 will look better but if your viewing mostly on 1080p to 60FPS as it is crazy smooth.

    I mean even though you make not see the full 4k visuals, its still going to look extremely crisp lol.
