Advantage of 4K

The image quality of using DANNOVO 4K Ultra HD camera is better than 2.0 Mega Pixels camera, the resolution is higher, the detailed level of the picture is more accurate, the image displayed is clearer, cleaner and more immersive, which can effectively meet the need of demanding high definition image quality in complicated lighting environment. In the 4K resolution, users will be able to see every detail in the picture, every close-up.

What’s 4K Resolution?

4K resolution, also called 4K, refers to a horizontal screen display resolution in the order of 4,000 pixels. There are several different 4K resolutions in the fields of digital television and digital cinematography. In television and consumer media, 3840 × 2160 (4K UHD) is the dominant 4K standard. In the movie projection industry, 4096 × 2160 (DCI 4K) is the dominant 4K standard.


Resolution of 3840 × 2160 has an aspect ratio of 16:9, with 8,294,400 total pixels. It is exactly double the horizontal and vertical resolution of 1080p (1920 × 1080) for a total of 4 times as many pixels, and triple the horizontal and vertical resolution of 720p (1280 × 720) for a total of 9 times as many pixels. It is sometimes referred to as "2160P", based on the naming patterns established by the previous 720P and 1080P HDTV standards.


Recording

The main advantage of recording video at the 4K standard is that fine spatial detail is resolved well. If the final video quality is reduced to 2K from a 4K recording, more detail is apparent than would have been achieved from a 2K recording. Increased fineness and contrast is then possible with output to DVD and Blu-ray. Some cinematographers choose to record at 4K when using the Super 35 film format to offset any resolution loss which may occur during video processing.
