4k

Definition

4k refers to a resolution standard of approximately 4000 pixels across the horizontal axis, specifically 3840 x 2160 pixels for consumer televisions and 4096 x 2160 pixels for digital cinema. This high resolution allows for greater detail and clarity in images, making it increasingly important in video cameras and the exporting process of digital content. With its enhanced pixel density, 4k provides filmmakers and content creators with the ability to capture and present stunning visuals that can be displayed on large screens without loss of quality.
