With 4k TVs, projectors and computer displays entering the marketplace in droves it is only a matter of time until 4k finds it’s way into the super slow motion realm for TV, Cinema and scientific analysis.
There is a strong argument for the increased resolution when it comes to capturing at 4k in any frame rate. It gives freedom to crop or punch in for a Full HD shot and or stabilize footage with crop leeway on the borders without trashing a shot. It is also crisp in a way that can only be described as looking through a window; which is a funny analogy because when Full HD came out in the early 2000s that was used often to sell TVs and the new experience. Now we are told the real window is 4k and your perfectly functional 1080p 240Hz tv is next to useless. This is of course hardly a realistic view or currently installed TV technology.
