Question: what are 4k video cameras?
Answer: 4K video refers to a display with at least 8 million active pixels. The resolution you'll see on TVs that support 4K is 3,840 by 2,160. For cameras, the resolution is 4,096 by 2,160. Compare that to the previous standard – HD, which was 1080p (1,920 by 1080). ... 4K is much sharper and results in higher clarity.
