4K is known as Ultra High Definition (UHD), whilst 1080P is simply labelled High Definition. As their names imply, 4K UHD has a considerably higher resolution than 1080P HD video. 4K resolution is exactly 3840 x 2160 pixels, whilst 1080P consists of 1920 x 1080 pixels.
The 4K designation refers to the close to 4000 horizontal pixels. Traditionally, resolution had been labelled according to vertical pixels and in the case of 1080P, 1080 vertical lines make up that high definition resolution. By comparison, 4K features 2160 pixels vertically; a considerable increase.
At an aspect ratio of 16:9, 4K contains almost four times the number of pixels on a screen compared with 1080P technology - more than eight million pixels for 4K and just two million pixels for 1080P. This massive difference brings about some important advantages for 4K when one compares it to the quality of a 1080P video.
Often times, a recording will need to be scaled down to a lower resolution. In the case of 4K, one may wish to downscale to a 2K high definition output. Tests have shown that when comparing the final video quality of a 4K video which has been downscaled to 2K, the picture is noticeably more detailed than could have resulted from originally creating the recording in 2K.
For people who want and expect the absolute highest possible quality motion picture experience, 4K is ticking all the boxes. From both a production point of view, and a viewing point of view, this ultra high definition technology is going to change the way we watch videos.
Television brands such as Sony are now selling 4K televisions at prices that the enthusiast can afford, and more and more video content is bring produced in 4K. Additionally, it's only a matter of time before DSLR consumer cameras are equipped with 4K video abilities; and the Canon 1DC DSLR hybrid has already reached that milestone.
All of this adds up to 4K becoming a technology that is no longer only in the hands of big production companies, but can be in the hands of the everyday video shooter and those who simply love to view their motion pictures in the most highly detailed format possible.
