What is the use of 4K Video?

Jul-18,2018

Have you ever shot a video for a client, only to have them come back later and tell you they need a still image for an advertisement or marketing campaign? 4K to the rescue. Although it only has twice as many horizontal lines as HD video, 4K footage has four times the total resolution of HD. While you can seek out a 2MP still image from standard HD video, that's not enough to be useful for anything much beyond online use. 4K, however, gives you the ability to extract an ~8MP image from your video. That's enough for a nice sized print or even an ad in a magazine.
