What is a 4K video ?

4K is a video quality that contains twice as many pixels as a Full HD film. A 4K video is distinguished by a sharper image. The 'K' in '4K' stands for Kilo (one thousand). 

Many videos and films are still delivered in FHD quality. With a 4K video, the film editor can then "zoom in" extra without resulting in lower quality. This gives more freedom in installation. Image quality is more than just the number of pixels. Read more about different video formats here .
